The AD5170 is a 256-position, two-time programmable I2C digital potentiometer from Analog Devices. It features fast settling time, low temperature coefficient and low power consumption.
The AD5170 digital potentiometer from Analog Devices provides 256 discrete resistance steps and features a unique two‑time programmable (TTP) architecture that allows a set‑and‑forget adjustment followed by a one‑time permanent programming. It operates from a single 2.7 V to 5.5 V supply and supports a standard 2‑wire I²C‑compatible serial interface for easy integration.
Its specifications include low power consumption (Ipp = 6 pA), a wide temperature range (‑40 °C to +125 °C), and a low temperature coefficient of 35 ppm/°C. The device is offered in a compact 10‑lead MSOP package and includes optional evaluation board and software tools for programming and testing.
