INPUT COMMON MODE VOLTAGE vs TEMPERATURE FN6247 Rev 11.00 September 8, 2015 Page 11 of 19 ISL28190, ISL28290 Applications Information Product Description The ISL28190 and ISL28290 are voltage feedback operational amplifiers designed for communication and imaging applications requiring low distortion, very low voltage and current noise. Both parts feature high bandwidth while drawing moderately low supply current. The ISL28190 and ISL28290 use a classical voltage-feedback topology, which allows them to be used in a variety of applications where current-feedback amplifiers are not appropriate because of restrictions placed upon the feedback element used with the amplifier. Using Only One Channel The ISL28290 is a Dual channel op amp. If the application only requires one channel when using the ISL28290, the user must configure the unused channel to prevent it from oscillating. Oscillation can occur if the input and output pins are floating. This will result in higher than expected supply currents and possible noise injection into the channel being used. The proper way to prevent this oscillation is to short the output to the negative input and ground the positive input (as shown in Figure 31). - Enable/Power-Down + The ISL28190 and ISL28290 amplifiers are disabled by applying a voltage greater than 2V to the EN pin, with respect to the V- pin. In this condition, the output(s) will be in a high impedance state and the amplifier(s) current will be reduced to 13A/Amp. By disabling the part, multiple parts can be connected together as a MUX. The outputs are tied together in parallel and a channel can be selected by the EN pin. The EN pin also has an internal pull-down. If left open, the EN pin will pull to the negative rail and the device will be enabled by default. Input Protection All input terminals have internal ESD protection diodes to both positive and negative supply rails, limiting the input voltage to within one diode beyond the supply rails. Both parts have additional back-to-back diodes across the input terminals (as shown in Figure 30). In pulse applications where the input Slew Rate exceeds the Slew Rate of the amplifier, the possibility exists for the input protection diodes to become forward biased. This can cause excessive input current and distortion at the outputs. If overdriving the inputs is necessary, the external input current must never exceed 5mA. An external series resistor may be used to limit the current, as shown in Figure 30. R + FIGURE 30. LIMITING THE INPUT CURRENT TO LESS THAN 5mA FIGURE 31. PREVENTING OSCILLATIONS IN UNUSED CHANNELS Power Supply Bypassing and Printed Circuit Board Layout As with any high frequency device, good printed circuit board layout is necessary for optimum performance. Low impedance ground plane construction is essential. Surface mount components are recommended, but if leaded components are used, 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 4.7F tantalum capacitor in parallel with a 0.01F capacitor has been shown to work well when placed at each supply pin. For good AC performance, parasitic capacitance should be kept to a minimum, especially at the inverting input. When ground plane construction is used, 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 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 additional peaking and overshoot. Current Limiting The ISL28190 and ISL28290 have no internal current-limiting circuitry. If the output is shorted, it is possible to exceed the Absolute Maximum Rating for output current or power dissipation, potentially resulting in the destruction of the device. This is why output short circuit current is specified and tested with RL = 10. FN6247 Rev 11.00 September 8, 2015 Page 12 of 19 ISL28190, ISL28290 Power Dissipation It is possible to exceed the +125C maximum junction temperatures under certain load and power-supply conditions. It is therefore important to calculate the maximum junction temperature (TJMAX) for all applications to determine if power supply voltages, load conditions, or package type need to be modified to remain in the safe operating area. These parameters are related as follows: (EQ. 1) T JMAX = T MAX + JA xPD MAXTOTAL where: * PDMAXTOTAL is the sum of the maximum power dissipation of each amplifier in the package (PDMAX) * PDMAX for each amplifier can be calculated as follows: V OUTMAX PD MAX = 2*V S I SMAX + V S - V OUTMAX ---------------------------R L (EQ. 2) where TMAX = Maximum ambient temperature * JA = Thermal resistance of the package * PDMAX = Maximum power dissipation of 1 amplifier * VS = Supply voltage * IMAX = Maximum supply current of 1 amplifier * VOUTMAX = Maximum output voltage swing of the application * RL = Load resistance FN6247 Rev 11.00 September 8, 2015 Page 13 of 19 ISL28190, ISL28290 Revision History The revision history provided is for informational purposes only and is believed to be accurate, but not warranted.
