GENERAL DESCRIPTION
The AD5280/AD5282 provides a single/dual channel, 256 position
digitally-controlled variable resistor (VR) device. These devices
perform the same electronic adjustment function as a
potentiometer, trimmer or variable resistor. Each VR offers a
completely programmable value of resistance, between the A
terminal and the wiper, or the B terminal and the wiper. The fixed
A-to-B terminal resistance of 20, 50 or 200K ohms has a 1%
channel-to-channel matching tolerance with a nominal temperature
coefficient of 30 ppm/°C.
Wiper Position programming defaults to midscale at system power
ON. Once powered the VR wiper position is programmed by a I

C
compatible 2-wire serial data interface. Both parts have two
programmable logic outputs available to drive digital loads, gates,
LED drivers, analog switches, etc.
