GENERAL DESCRIPTION

Wiper position programming presets to midscale upon power-

on. Once powered, the VR wiper position is programmed by

either the 3-wire SPI or 2-wire I²C-compatible interface. In the

I²C mode, additional programmable logic outputs enable users

to drive digital loads, logic gates, and analog switches in their

systems.

The AD5263 is the industry’s first quad-channel, 256-position,

digital potentiometer¹with a selectable digital interface. This

device performs the same electronic adjustment function as

mechanical potentiometers or variable resistors, with enhanced

resolution, solid-state reliability, and superior low temperature

coefficient performance.

The AD5263 is available in a narrow body, 24-lead TSSOP.

All parts are guaranteed to operate over the automotive

temperature range of –40°C to +125°C.

Each channel of the AD5263 offers a completely programmable

value of resistance between the A terminal and the wiper or

between the B terminal and the wiper. The fixed A-to-B

terminal resistance of 20 kΩ, 50 kΩ, or 200 kΩ has a nominal

temperature coefficient of 30 ppm/°C and a 1% channel-to-

channel matching tolerance. Another key feature of this part is

the ability to operate from +4.5 V to +15 V, or at 5 V.

For single- or dual-channel applications, refer to the

AD5260/AD5280 or AD5262/AD5282 data sheets.

¹The terms digital potentiometer, VR, and RDAC are used interchangeably.
