GENERAL DESCRIPTION  
The AD5241/AD5242 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. For  
AD5242, the fixed A-to-B terminal resistance of 10 kΩ, 100 kΩ  
or 1 MΩ has a 1% channel-to-channel matching tolerance.  
Nominal temperature coefficient of both parts is 30 ppm/°C.

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

The AD5241/AD5242 is available in surface-mount (SO-14/-16)  
packages and, for ultracompact solutions, TSSOP-14/-16 pack-  
ages. 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, please refer to AD5200,  
AD5201, AD5203, AD5204, AD5206, AD5231*, AD5232*,  
AD5235*, AD7376, AD8400, AD8402, and AD8403 products.  
*Nonvolatile digital potentiometer.
