GENERAL DESCRIPTION  
AD5280  
The AD5280/AD5282 are single-channel and dual-channel,  
256-position, digitally controlled variable resistors (VRs)2.  
The 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 kΩ, 50 kΩ, or 200 kΩ has  
a 1% channel-to-channel matching tolerance. The nominal  
temperature coefficient of both parts is 30 parts per million/  
degrees centigrade (ppm/°C). Another key feature is that the  
parts can operate up to +15 V or 5 V.

Wiper position programming defaults to midscale at system  
power-on. When powered, the VR wiper position is programmed  
by an I2C-compatible, 2-wire serial data interface. The AD5280/  
AD5282 feature sleep mode programmability. This allows any  
level of preset in power-up and is an alternative to a costly  
EEPROM solution. Both parts have additional programmable
