On the output, the amplifiers can swing within 200 mV of either supply rail.With their combination of low price, excellent differential gain (0.2%), differential phase (0.10), and 0.5 dB flatness out to 22 MHz, these amplifiers are ideal for video applications. 6.5 6.4 0.1V p-p VS = 5V RL = 150 G = +2 6.3 6.2 6.1 2.0V p-p 6.0 5.9 5.8 5.7 05884-010 The ADA4853-1/ADA4853-2/ADA4853-3 voltage feedback op amps are designed to operate at supply voltages as low as 2.65 V and up to 5 V using only 1.4 mA of supply current per amplifier. To further reduce power consumption, the amplifiers are equipped with a disable mode that lowers the supply current to less than 1.5 A maximum, making them ideal in battery-powered applications. The ADA4853-1 is available in a 6-lead SC70, the ADA4853-2 is available in a 16-lead LFCSP_VQ, and the ADA4853-3 is available in both a 16-lead LFCSP_VQ and a 14-lead TSSOP. The ADA4853-1 temperature range is -40C to +85C while the ADA4853-2/ ADA4853-3 temperature range is -40C to +105C. CLOSED-LOOP GAIN (dB) The ADA4853-1/ADA4853-2/ADA4853-3 are low power, low cost, high speed, rail-to-rail output op amps with ultralow power disables that are ideal for portable consumer electronics. Despite their low price, the ADA4853-1/ADA4853-2/ADA4853-3 provide excellent overall performance and versatility. The 100 MHz, -3 dB bandwidth, and 120 V/s slew rate make these amplifiers wellsuited for many general-purpose, high speed applications. 5.6 5.5 0.1 1 FREQUENCY (MHz) 10 40 Figure 5. 0.5 dB Flatness Frequency Response Rev.

Figure 6 shows the maximum safe power dissipation in the package vs. the ambient temperature for the 6-lead SC70 (430C/W), the 14-lead TSSOP (120C/W), and the 16-lead LFCSP_VQ (63C/W) on a JEDEC standard 4-layer board. JA values are approximations. 3.0 THERMAL RESISTANCE JA is specified for the worst-case conditions, that is, JA is specified for the device soldered in the circuit board for surface-mount packages.

In addition, more metal directly in contact with the package leads and through holes under the device reduces JA. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied.

Figure 6. Maximum Power Dissipation vs. Temperature for a 4-Layer Board Maximum Power Dissipation The maximum safe power dissipation for the ADA4853-1/ ADA4853-2/ADA4853-3 is limited by the associated rise in junction temperature (TJ) on the die. At approximately 150C, which is the glass transition temperature, the plastic changes its properties. Even temporarily exceeding this temperature limit can change the stresses that the package exerts on the die, permanently shifting the parametric performance of the amplifiers. Exceeding a junction temperature of 150C for an extended period can result in changes in silicon devices, potentially causing degradation or loss of functionality. ESD CAUTION Rev.

F | Page 15 of 20 200 05884-055 6 ADA4853-1/ADA4853-2/ADA4853-3 CIRCUIT DESCRIPTION The ADA4853-1/ADA4853-2/ADA4853-3 feature a high slew rate input stage that is a true single-supply topology capable of sensing signals at or below the minus supply rail. The rail-torail output stage can pull within 100 mV of either supply rail when driving light loads and within 200 mV when driving 150 . High speed performance is maintained at supply voltages as low as 2.65 V. HEADROOM CONSIDERATIONS For signals approaching the negative supply, inverting gain, and high positive gain configurations, the headroom limit is the output stage. The ADA4853-1/ADA4853-2/ADA4853-3 use a common-emitter output stage. This output stage maximizes the available output range, limited by the saturation voltage of the output transistors. The saturation voltage increases with the drive current that the output transistor is required to supply due to the collector resistance of the output transistor. The ADA4853-1/ADA4853-2/ADA4853-3 are designed for use in low voltage systems. To obtain optimum performance, it is useful to understand the behavior of the amplifiers as input and output signals approach their headroom limits. The input common-mode voltage range of the amplifier extends from the negative supply voltage (actually 200 mV below this) to within 1.2 V of the positive supply voltage. As the saturation point of the output stage is approached, the output signal shows increasing amounts of compression and clipping. For the input headroom case, higher frequency signals require a bit more headroom than the lower frequency signals. Figure 27 illustrates this point by plotting the typical distortion vs. the output amplitude. OVERLOAD BEHAVIOR AND RECOVERY Exceeding the headroom limits is not a concern for any inverting gain on any supply voltage, as long as the reference voltage at the positive input of the amplifier lies within the a input common-mode range of the amplifier. Input The input stage is the headroom limit for signals approaching the positive rail. Figure 50 shows a typical offset voltage vs. the input common-mode voltage for the ADA4853-1/ADA4853-2/ ADA4853-3 on a 5 V supply. Accurate dc performance is maintained from approximately 200 mV below the negative supply to within 1.2 V of the positive supply. For high speed signals, however, there are other considerations. As the common-mode voltage gets within 1.2 V of positive supply, the amplifier responds well but the bandwidth begins to drop as the common-mode voltage approaches the positive supply. This can manifest itself in increased distortion or settling time. Higher frequency signals require more headroom than the lower frequencies to maintain distortion performance. The specified input common-mode voltage of the ADA4853-1/ ADA4853-2/ADA4853-3 is 200 mV below the negative supply to within 1.2 V of the positive supply. Exceeding the top limit results in lower bandwidth and increased rise time. Pushing the input voltage of a unity-gain follower to less than 1.2 V from the positive supply leads to an increasing amount of output error as well as increased settling time. The recovery time from input voltages 1.2 V or closer to the positive supply is approximately 40 ns; this is limited by the settling artifacts caused by transistors in the input stage coming out of saturation. The amplifiers do not exhibit phase reversal, even for input voltages beyond the voltage supply rails. Going more than 0.6 V beyond the power supplies turns on protection diodes at the input stage, greatly increasing the current draw of the devices. -0.6 VS = 5V -0.8 -1.2 -1.4 -1.6 -1.8 -2.0 -1.0 -0.5 0 0.5 1.0 1.5 2.0 VCM (V) 2.5 3.0 3.5 4.0 4.5 05884-022 VOS (mV) -1.0 Figure 50.

Figure 51 shows a typical video driver set for a noninverting gain of +2, where RF = RG = 1 k. The video amplifier input is terminated into a shunt 75 resistor. At the output, the amplifier has a series 75 resistor for impedance matching to the video load. As is the case with all high speed applications, careful attention to printed circuit board (PCB) layout details prevents associated board parasitics from becoming problematic. The ADA4853-1/ ADA4853-2/ADA4853-3 can operate at up to 100 MHz; therefore, proper RF design techniques must be employed. The PCB should have a ground plane covering all unused portions of the component side of the board to provide a low impedance return path. Removing the ground plane on all layers from the area near and under the input and output pins reduces stray capacitance. Signal lines connecting the feedback and gain resistors should be kept as short as possible to minimize the inductance and stray capacitance associated with these traces. Termination resistors and loads should be located as close as possible to their respective inputs and outputs. Input and output traces should be kept as far apart as possible to minimize coupling (crosstalk) through the board. Adherence to microstrip or stripline design techniques for long signal traces (greater than 1 inch) is recommended.

When operating in low voltage, single-supply applications, the input signal is only limited by the input stage headroom.

Video Amplifier POWER SUPPLY BYPASSING Attention must be paid to bypassing the power supply pins of the ADA4853-1/ADA4853-2/ADA4853-3. High quality capacitors with low equivalent series resistance (ESR), such as multilayer ceramic capacitors (MLCCs), should be used to minimize supply voltage ripple and power dissipation. A large, usually tantalum, 2.2 F to 47 F capacitor located in proximity to the ADA4853-1/ADA4853-2/ADA4853-3 is required to provide good decoupling for lower frequency signals. The actual value is determined by the circuit transient and frequency requirements. In addition, 0.1 F MLCC decoupling capacitors should be located as close to each of the power supply pins as is physically possible, no more than inch away. The ground returns should terminate immediately into the ground plane. Locating the bypass capacitor return close to the load return minimizes ground loops and improves performance. Rev.
