Description
AD5242BRUZ-10 is a dual-channel I2C digital potentiometer from Analog Devices. Each channel provides a 100 kΩ end-to-end potentiometer with 128-step (7-bit) wiper resolution, allowing two independent adjustable resistances (A–W and B–W configurations). Controlled via a two-wire I2C interface, it’s ideal for digitally trimming gain, attenuation, offsets, sensor calibration, and programmable analog front-ends in compact, low-power designs. The BRUZ suffix indicates a RoHS-compliant package (8-pin) in a tape-and-reel/host packaging option. Key points: dual pots, I2C control, 100 kΩ per pot, 128 wiper steps, small footprint, suitable for precision/adjustment tasks in embedded systems.
