Description

1, 8

TP

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

3, 7

NIC

No Internal Connect. NICs have no internal

connections.

GND

Ground Pin = 0 V

5

TRIM

Trim Terminal. It can be used to adjust the

output voltage over a

±0.5% range without

affecting the temperature coefficient.

ORDERING GUIDE

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.

WARNING!
