Feature Description (continued)

8.3.3 Diodes Between the Inputs

The LMP770x have a set of anti-parallel diodes between the input pins, as shown in Figure 45. These diodes are

present to protect the input stage of the amplifier. At the same time, they limit the amount of differential input

voltage that is allowed on the input pins. A differential signal larger than one diode voltage drop might damage

the diodes. The differential signal between the inputs needs to be limited to ±300 mV or the input current needs

to be limited to ±10 mA.
