Typical Applications Operation Below 15V Supply V+ 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. 7 2 Offset Adjustment RLIMIT The following is the recommended V IO adjust configuration: - 6 + +15V RLIMIT 7 1 3 + RP 4 3 8 6 2 V4 The Bias currents will increase when a differential voltage of 0.7V is exceeded. -15V Setting RP = 20K will give an adjustment range of ±2.6mV.
