CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD42x features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

PIN FUNCTION DESCRIPTIONS
Test Pin. There are actual connections in TP
pins but they are reserved for factory testing
purposes. Users should not connect any-
thing to TP pins, otherwise the device may
not function properly.
Input Voltage
No Internal Connect. NICs have no internal
connections.
Ground Pin = 0 V
Trim Terminal. It can be used to adjust the
output voltage over a ± 0.5% range without
affecting the temperature coefficient.
