GENERAL DESCRIPTION

The AD5241/AD5242 provide 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. The 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 are available in surface-mount (SOIC-14/-

16) packages and, for ultracompact solutions, TSSOP-14/-16

packages. All parts are guaranteed to operate over the

extended temperature range of –40°C to +105°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
