They will operate with dual supplies ranging from g 1.5V to g 6V, or from single supplies ranging from a 3V to a 12V. In spite of their low supply current, the EL2480C and the EL2280C can output 55 mA while swinging to g 4V on g 5V supplies. The EL2180C can output 100 mA with similar output swings. These attributes make the EL2180C/EL2280C/EL2480C excellent choices for low power and/or low voltage cable-driver, HDSL, or RGB applications. EL2180C/EL2280C/EL2480C EL2180C/EL2280C/EL2480C For applications where board space is extremely critical, the EL2180C is available in the tiny 5-lead SOT23 package, which has a footprint 28% the size of an 8-lead SOIC. For Single, Dual, and Triple applications with disable, consider the EL2186C (8-Pin Single), EL2286C (14-Pin Dual) or EL2386C (16-Pin Triple). For lower power applications where speed is still a concern, consider the EL2170C/El2176C family which also comes in similar Single, Dual and Quad configurations. The EL2170C/EL2176C family provides a b 3 dB bandwidth of 70 MHz while consuming 1 mA of supply current per amplifier.

Ground plane construction is highly recommended. Lead lengths should be as short as possible. The power supply pins must be well bypassed to reduce the risk of oscillation. The combination of a 4.7 mF tantalum capacitor in parallel with a 0.1 mF capacitor has been shown to work well when placed at each supply pin. The EL2180C/EL2280C/EL2480C are currentfeedback operational amplifiers that offer a wide b 3 dB bandwidth of 250 MHz and a low supply current of 3 mA per amplifier. All of these products also feature high output current drive. The EL2180C can output 100 mA, while the EL2280C and the EL2480C can output 55 mA per amplifier. The EL2180C/EL2280C/EL2480C work with supply voltages ranging from a single 3V to g 6V, and they are also capable of swinging to within 1V of either supply on the input and the output. Because of their current-feedback topology, the EL2180C/EL2280C/EL2480C do not have the normal gain-bandwidth product associated with voltage-feedback operational amplifiers. This allows their b 3 dB bandwidth to remain relatively constant as closed-loop gain is increased. This combination of high bandwidth and low power, together with aggressive pricing make the EL2180C/EL2280C/EL2480C the ideal choice for many low-power/high-bandwidth applications such as portable computing, HDSL, and video processing. For good AC performance, parasitic capacitance should be kept to a minimum especially at the inverting input (see the Capacitance at the Inverting Input section). Ground plane construction should be used, but it should be removed from the area near the inverting input to minimize any stray capacitance at that node. Carbon or Metal-Film resistors are acceptable with the Metal-Film resistors giving slightly less peaking and bandwidth because of their additional series inductance. Use of sockets, particularly for the SO package, should be avoided if possible. Sockets add parasitic inductance and capacitance which will result in some additional peaking and overshoot. For applications where board space is extremely critical, the EL2180C is available in the tiny 5-lead SOT23 package, which has a footprint 28% the size of an 8-lead SOIC. The EL2180C/ EL2280C/EL2480C are each also available in industry standard pinouts in PDIP and SOIC packages. Capacitance at the Inverting Input Any manufacturer's high-speed voltage- or current-feedback amplifier can be affected by stray capacitance at the inverting input. For inverting gains this parasitic capacitance has little effect because the inverting input is a virtual ground, but for non-inverting gains this capacitance (in conjunction with the feedback and gain resistors) creates a pole in the feedback path of the amplifier. This pole, if low enough in frequency, has the same destabilizing effect as a zero in the forward open-loop response. The use of large value feedback and gain resistors further exacerbates the problem by further lowering the pole frequency. For Single, Dual and Triple applications with disable, consider the EL2186C (8-Pin Single), EL2286C (14-Pin Dual) and EL2386C (16-Pin Triple). If lower power is required, refer to the EL2170C/EL2176C family which provides Singles, Duals, and Quads with 70 MHz of bandwidth while consuming 1 mA of supply current per amplifier. 10 EL2180C/EL2280C/EL2480C 250 MHz/3 mA Current Mode Feedback Amplifiers Supply Voltage Range and SingleSupply Operation Applications Information Contd. The experienced user with a large amount of PC board layout experience may find in rare cases that the EL2180C/EL2280C/EL2480C have less bandwidth than expected. The EL2180C/EL2280C/EL2480C have been designed to operate with supply voltages having a span of greater than 3V, and less than 12V. In practical terms, this means that the EL2180C/ EL2280C/EL2480C will operate on dual supplies ranging from g 1.5V to g 6V. With a single-supply, the EL2180C/EL2280C/EL2480C will operate from a 3V to a 12V. The reduction of feedback resistor values (or the addition of a very small amount of external capacitance at the inverting input, e.g. 0.5 pF) will increase bandwidth as desired. Please see the curves for Frequency Response for Various RF and RG, and Frequency Response for Various CIN b . As supply voltages continue to decrease, it becomes necessary to provide input and output voltage ranges that can get as close as possible to the supply voltages. The EL2180C/EL2280C/ EL2480C have an input voltage range that extends to within 1V of either supply. So, for example, on a single a 5V supply, the EL2180C/ EL2280C/EL2480C have an input range which spans from 1V to 4V. The output range of the EL2180C/EL2280C/EL2480C is also quite large, extending to within 1V of the supply rail. On a g 5V supply, the output is therefore capable of swinging from b 4V to a 4V. Single-supply output range is even larger because of the increased negative swing due to the external pull-down resistor to ground. On a single a 5V supply, output voltage range is about 0.3V to 4V. Feedback Resistor Values The EL2180C/EL2280C/EL2480C have been designed and specified at gains of a 1 and a 2 with RF e 750X in PDIP and SOIC packages and RF e 560X in SOT23-5 package. These values of feedback resistors give 250 MHz of b 3 dB bandwidth at AV e a 1 with about 2.5 dB of peaking, and 180 MHz of b 3 dB bandwidth at AV e a 2 with about 0.1 dB of peaking. The SOT23-5 package is characterized with a smaller value of feedback resistor, for a given bandwidth, to compensate for lower parasitics within both the package itself and the printed circuit board where it will be placed. Since the EL2180C/EL2280C/ EL2480C are current-feedback amplifiers, it is also possible to change the value of RF to get more bandwidth. As seen in the curve of Frequency Response For Various RF and RG, bandwidth and peaking can be easily modified by varying the value of the feedback resistor. Video Performance For good video performance, an amplifier is required to maintain the same output impedance and the same frequency response as DC levels are changed at the output. This is especially difficult when driving a standard video load of 150X, because of the change in output current with DC level. Until the EL2180C/EL2280C/EL2480C, good Differential Gain could only be achieved by running high idle currents through the output transistors (to reduce variations in output impedance). These currents were typically comparable to the entire 3 mA supply current of each EL2180C/EL2280C/EL2480C amplifier! Special circuitry has been incorporated in the EL2180C/ EL2280C/EL2480C to reduce the variation of output impedance with current output. This results in dG and dP specifications of 0.05% and 0.05 while driving 150X at a gain of a 2. Because the EL2180C/EL2280C/EL2480C are current-feedback amplifiers, their gain-bandwidth product is not a constant for different closed-loop gains. This feature actually allows the EL2180C/EL2280C/EL2480C to maintain about the same b 3 dB bandwidth, regardless of closed-loop gain. However, as closed-loop gain is increased, bandwidth decreases slightly while stability increases. Since the loop stability is improving with higher closed-loop gains, it becomes possible to reduce the value of RF below the specified 560X and 750X and still retain stability, resulting in only a slight loss of bandwidth with increased closed-loop gain. 11 EL2180C/EL2280C/EL2480C 250 MHz/3 mA Current Mode Feedback Amplifiers Applications Information Contd. Current Limiting Video Performance has also been measured with a 500X load at a gain of a 1. Under these conditions, the EL2180C/EL2280C/EL2480C have dG and dP specifications of 0.01% and 0.01 respectively while driving 500X at AV e a 1. The EL2180C/EL2280C/EL2480C have no internal current-limiting circuitry. If any output is shorted, it is possible to exceed the Absolute Maximum Ratings for output current or power dissipation, potentially resulting in the destruction of the device. Output Drive Capability Power Dissipation In spite of its low 3 mA of supply current, the EL2180C is capable of providing a minimum of g 80 mA of output current. Similarly, each amplifier of the EL2280C and the EL2480C is capable of providing a minimum of g 50 mA. These output drive levels are unprecedented in amplifiers running at these supply currents. With a minimum g 80 mA of output drive, the EL2180C is capable of driving 50X loads to g 4V, making it an excellent choice for driving isolation transformers in telecommunications applications. Similarly, the g 50 mA minimum output drive of each EL2280C and EL2480C amplifier allows swings of g 2.5V into 50X loads. With the high output drive capability of the EL2180C/EL2280C/EL2480C, it is possible to exceed the 150 C Absolute Maximum junction temperature under certain very high load current conditions. Generally speaking, when RL falls below about 25X, it is important to calculate the maximum junction temperature (TJmax) for the application to determine if power-supply voltages, load conditions, or package type need to be modified for the EL2180C/EL2280C/EL2480C to remain in the safe operating area. These parameters are calculated as follows: [1] TJMAX e TMAX a (iJA * n * PDMAX) Driving Cables and Capacitive Loads where: TMAX iJA n When used as a cable driver, double termination is always recommended for reflection-free performance. For those applications, the back-termination series resistor will decouple the EL2180C/ EL2280C/EL2480C from the cable and allow extensive capacitive drive. However, other applications may have high capacitive loads without a back-termination resistor. In these applications, a small series resistor (usually between 5X and 50X) can be placed in series with the output to eliminate most peaking. The gain resistor (RG) can then be chosen to make up for any gain loss which may be created by this additional resistor at the output. In many cases it is also possible to simply increase the value of the feedback resistor (RF) to reduce the peaking. e Maximum Ambient Temperature e Thermal Resistance of the Package e Number of Amplifiers in the Pack- age PDMAX e Maximum Power Dissipation of Each Amplifier in the Package.
