Description
AD5293BRUZ-50 is a digitally controlled potentiometer (digipot) from Analog Devices. It provides a 50 kΩ end-to-end resistance with a digitally programmable wiper, typically offering 256 positions (8-bit resolution) controlled via a serial interface. It’s designed for single-supply operation (common voltage ranges around 2.7–5.5 V) and is suitable for applications like programmable gain/attenuation, offset trimming, and sensor calibration in analog front-ends. The BRUZ-50 suffix indicates the packaging/lead finish and the 50 kΩ end value. For exact specifications, timing diagrams, and package details, refer to the AD5293 data sheet.
Equivalent
Direct equivalents aren’t one-to-one; cross-refs depend on specs. The AD5293BRUZ-50 is a 256-tap digital potentiometer with SPI interface and a defined end-to-end resistance, voltage range, package, and temperature rating. To provide equivalents, please share: end-to-end resistance (e.g., 5kΩ/10kΩ), number of taps (256), interface (SPI/I2C), voltage range, package, and temp. With that, I can suggest closest 256-tap digi-pot matches from TI, Microchip, Onsemi, etc.

Pinout
- Pin count: 8 pins (8-pin package).
- Function: A single-channel digital potentiometer with end-to-end resistance of 50 kΩ. It has terminals A, B, and W (wiper) plus VDD and VSS, and is controlled by a 3-wire SPI-like serial interface (CS, SCLK, SI). It digitally sets the wiper position to vary the resistance between A–W or W–B in analog circuits.
