Pin 14 Current Comments

Minimum pin 14 current required for shutdown is 05 mA and must not exceed 1 mA

Maximum pin 14 current for amplifier not shut down is 005 mA

The typical shutdown switch point current is 02 mA

Note 1

For operation in ambient temperatures above 25 C the device must be derated based on a 150 C maximum junction temperature and a thermal resistance

of 90 CW junction to ambient
