6.3.3 Diodes Between the Inputs

The LMP7704-SP have a set of antiparallel diodes between the input pins, as shown in Figure 6-1. These diodes are present to protect the input stage of the amplifier. At the same time, the diodes limit the amount of differential input voltage that is allowed on the input pins. A differential signal larger than a one-diode voltage drop can damage the diodes. Limit the differential signal between the inputs to ±300 mV or limit the input current to ±10 mA.
