HA-5177
Typical Applications
Operation Below 15V Supply
The HA-5177 performs well down to ±5V supplies. At ±5V
supplies there is a slight degradation of slew rate and open
loop gain. There is very little change in bias currents and
offset voltage.
Offset Adjustment
The following is the recommended VIO adjust configuration:

The HA-5177 input stage has built in back-to-back protection
diodes with series current limiting resistors.

The Bias currents will increase when a differential voltage of
0.7V is exceeded.
Setting RP = 20K will give an adjustment range of ±2.6mV.
Input Protection
The internal current limiting resistors sufficiently limit current
therefore, no external resistors are required.
Refer to the ‘‘Bias Current vs Differential Input Voltage’’
curve in the Typical Performance Curves.
