Overview
The AD5292BRUZ-20, produced by Analog Devices Inc., is a single-channel, 1024-position digital potentiometer. This device combines industry-leading variable resistor performance with nonvolatile memory (NVM) in a compact 14-lead TSSOP package. It is designed to operate 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. The AD5292BRUZ-20 features a maximum ±1% nominal resistor tolerance error, making it suitable for precision calibration and tolerance matching applications.
