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.  
The AD5280/AD5282 are available in ultra compact surface mount  
thin TSSOP-14/-16 packages. All parts are guaranteed to operate  
over the extended industrial temperature range of -40°C to +85°C.  
For 3-wire, SPI compatible interface applications, see  
AD5203/AD5204/AD5206/AD7376/AD8400/AD8402/AD8403/

Wiper Position programming defaults to midscale at system power  
ON. Once powered the VR wiper position is programmed by a I2C  
compatible 2-wire serial data interface. Both parts have two  
programmable logic outputs available to drive digital loads, gates,  
LED drivers, analog switches, etc.
