Input Differential Voltage Protection

During normal op-amp operation, the inverting and non-

inverting inputs of the MAX9945 are at approximately

the same voltage. The ±12V absolute maximum input

differential voltage rating offers sufficient protection for

most applications. If there is a possibility of exceeding

the input differential voltage specification, in the pres-

ence of extremely fast input voltage transients or due to

certain application-specific fault conditions, use exter-

nal low-leakage pico-amp diodes and series resistors

to protect the input stage of the amplifier (see Figure 2).

The extremely low input bias current of the MAX9945

allows a wide range of input series resistors to be used.

If low input voltage noise is critical to the application,

size the input series resistors appropriately.
