The AD5293 is a single-channel digital potentiometer with 1024-position resolution and 1% R-tolerance. It features a SPI-compatible serial interface and can be used as a replacement for mechanical potentiometers for applications such as gain and offset adjustment, programmable voltage-to-current conversion, programmable filters, delays, and time constants, as well as sensor calibration.
The AD5293 is a single‑channel, 1024‑position digital potentiometer that offers a calibrated 1 % nominal resistor tolerance and low temperature‑coefficient performance. It operates from 9 V to 33 V on a single supply or +9 V to +16.5 V on dual supplies and is available in a compact 14‑lead TSSOP package.
Typical applications include replacing mechanical potentiometers, gain and offset adjustment in instrumentation, programmable voltage‑to‑current conversion, audio volume control, and high‑voltage DAC functions. Ordering information and package options are listed at the end of the document.
