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 the

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. When powered, the VR wiper position is programmed

by an I²C®-compatible, 2-wire serial data interface. Both parts

have two extra programmable logic outputs available 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, 14-lead

SOIC and 16-lead SOIC packages and, for ultracompact solutions,

14-lead TSSOP and 16-lead TSSOP packages. All parts are

guaranteed to operate over the extended temperature range of

−40°C to +105°C.
