Low resolution DAC replacement

Sensor calibration

The AD5291/2 device wiper settings are controllable through

the SPI digital interface. Unlimited adjustments are allowed

before programming the resistance value into the 20-TP (20

Time Programmable) memory. The AD5291/2 do not require

any external voltage supply to facilitate fuse blow and there are

20 opportunities for permanent programming. During 20-TP

activation, a permanent blow fuse command freezes the wiper

position (analogous to placing epoxy on a mechanical trimmer).

GENERAL DESCRIPTION

The AD5291/2 are single-channel, 256/1024-position digital

potentiometers¹with less than 1% end-to-end Resistor

Tolerance error and 20-Time Programmable Memory. The

AD5291/2 perform the same electronic adjustment function as

a mechanical potentiometer with enhanced resolution, solid

state reliability, and superior low temperature coefficient

performance. These devices are capable of operating at high-

voltages; supporting both dual supply 10.5 to 15ꢀ and single

supply operation +21ꢀ to +30ꢀ.

The AD5291/2 are available in a compact 14ld TSSOP package.

The part is guaranteed to operate over the extended industrial

temperature range of −40°C to +105°C.

The AD5291/2 offer guaranteed industry leading low resistor

tolerance errors of ±1% with a nominal temperature coefficient

of 35 ppm/ºC. The low resistor tolerance feature simplifies

open-loop applications as well as precision calibration and

tolerance matching applications.

¹The terms digital potentiometer and RDAC are used interchangeably.
