Analog Devices AD5253/AD5254 Digital Potentiometer Product Handbook
The AD5253/AD5254 are quad‑channel I²C digital potentiometers that provide nonvolatile memory for wiper settings. They offer 64‑step resolution for the AD5253 and 256‑step resolution for the AD5254, with selectable resistance values of 1 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ. Features include write‑protectable EEMEM, synchronous or asynchronous channel updates, and a +6 dB step‑change command.
Typical applications are mechanical potentiometer replacement, low‑resolution DAC replacement, LED backlight control, RF power‑amp bias, programmable gain/offset, and sensor calibration. The devices are supplied in a TSSOP‑20 package and operate over a wide temperature range, making them suitable for industrial and consumer electronics.
