The AD5291 and AD5292 are single-channel, 256-/1024-position digital potentiometers that combine industry leading variable resistor performance with nonvolatile memory (NVM) in a compact package. These devices are capable of operating 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.

EVAL-AD5292
AD5292 Evaluation Board
Product Detail
This user guide describes the full featured EVAL-AD5292DBZ board for evaluating the AD5292 digital potentiometer. The AD5292 is a single-channel, 1024-position digital potentiometer with less than ±1% end to end resistor tolerance error and 20-time programmable (20-TP) memory. The AD5292 is capable of operating at high voltages, supporting both dual supply ±10.5 V to ±16.5 V and single supply 21 V to 33 V operation.
The AD5292 uses a serial interface that operates at clock rates of up to 50 MHz and is compatible with the standard serial peripheral interface (SPI).
The EVAL-AD5292DBZ incorporates an internal power supply from the USB and allows an external power supply for the logic voltage levels. The logic voltage levels operate from single 2.7 V to 5.5 V supplies. The EVAL-AD5292DBZ can operate in single supply and dual supply modes, and incorporates an output buffer.
Complete specifications for the AD5292 can be found in the AD5292 data sheet available from Analog Devices, Inc., and must be consulted in conjunction with this user guide when using the evaluation board.
