AD5165 is a ultralow power digital potentiometer from Analog Devices, with a working voltage of 1.8V, a maximum resistance of 100kΩ and supports 256 positions, suitable for battery powered electronic devices, remote utility meter adjustment, mechanical potentiometer replacement, transducer circuit adjustment, automotive electronic equipment adjustment, gain control and offset adjustment, system calibration, VCXO adjustment and other applications.
The AD5165 provides a compact 2.9 mm × 2.8 mm solution for 256‑position adjustment applications. It operates from a 2.7 V to 5.5 V supply and consumes less than 50 nA standby current, making it ideal for battery‑operated devices. The device uses a simple 3‑wire digital interface compatible with SPI‑style communication.
Typical performance includes a low temperature coefficient of 35 ppm/°C, an operating temperature range of –40 °C to +125 °C, and a resolution of 8 bits (256 positions). The datasheet also details pin configuration, timing characteristics, ESD protection, and recommended layout and power‑supply bypassing practices.
