AD5165 is a compact 2.9 mm × 2.8 mm packaged solution for 256-position adjustment applications. It consumes only 50 nA of standby power, has a 2.7 V to 5.5 V power supply voltage, a 100 kΩ resistance range, a 35 ppm/°C temperature coefficient, a simple 3-wire digital interface, and a wide operating temperature range of -40°C to +125°C. The AD5165 is suitable for applications such as battery-operated electronic adjustment, remote utility meter adjustment, mechanical potentiometer replacement, transducer circuit adjustment, automotive electronic adjustment, gain control and offset adjustment, system calibration, and VCXO adjustment.
The AD5165 digital potentiometer offers 256 positions with an end‑to‑end resistance of 100 kΩ. It operates from a 2.7 V to 5.5 V supply and uses a simple 3‑wire digital interface compatible with SPI, with an inverted chip‑select to reduce standby power.
Designed for battery‑operated electronics, the device features ultralow standby current (≈50 nA), a low temperature coefficient (35 ppm/°C), and a wide operating temperature range from –40 °C to +125 °C. The thin TSOT‑8 package (2.9 mm × 2.8 mm) makes it suitable for space‑constrained applications.
