Input Differential Voltage Protection
Chip Information
During normal op-amp operation, the inverting and non-
PROCESS: BiCMOS
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.
