AD5293

Single Channel, 1024-Position, 1% R-Tol, Digital Potentiometer
Manufactured by:

Product Details

The AD5293 is a single-channel, 1024-position digital potentiometer1 with <1% end-to-end resistor tolerance error. The AD5293 performs the same electronic adjustment function as a mechanical potentiometer with enhanced resolution, solid state reliability, and superior low temperature coefficient performance. This device is capable of operating at high voltages and supporting both dual-supply operation at ±10.5 V to ±15 V and single-supply operation at 21 V to 33 V.

The AD5293 offers guaranteed industry-leading low resistor tolerance errors of ±1% with a nominal temperature coefficient of 35 ppm/°C. The low resistor tolerance feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.

The AD5293 is available in a compact 14-lead TSSOP package. The part is guaranteed to operate over the extended industrial temperature range of −40°C to +105°C.

1In this data sheet, the terms digital potentiometer and RDAC are used interchangeably.

I ordered the samples for evaluation, but the minimal amount of 1 component is very limiting. when I had some problems with the prototype board, I had no second device to try and test it on another, and spent a lot of time trying to figure out the reason for the impropper functionality of the board.

Clear and easy instruction and samples in the manuells, so I can use the chip wtihout correction of the assembler program of the microcontroller

Digital potetiometer
The potentiometer works as expected, it has more taps than most competitors. It would be nice to have a higher current version.

Solderable package which is a big plus for prototyping. Much better accuracy and number of taps than the competition.
