Single Channel, 1024-Position, 1% R-Tol, Digital Potentiometer with 20-Times Programmable Memory
Manufactured by:

Product Details

The AD5292 is a single-channel, 1024-position digital potentiometers1 that combines industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package. These devices are capable of operat-ing across a wide voltage range, supporting both dual supply operation at ±10.5 V to ±16.5 V and single supply operation at +21 V to +33 V, while ensuring less than 1% end-to-end resistor tolerance error and offering 20-time programmable (20-TP) memory.

The guaranteed industry leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.

The AD5291 and AD5292 device wiper settings are controllable through the SPI digital interface. Unlimited adjustments are allowed before programming the resistance value into the 20-TP memory. The AD5291 and AD5292 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).

The AD5291 and AD5292 are 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.

The AD5292-EP supports defense and aerospace applications (AQEC)

1The terms digital potentiometer and RDAC are used interchangeably.
