AD5170 is a 256-position digital potentiometer with two-time programming and I2C interface produced by Analog Devices.
The AD5170 digital potentiometer provides 256 programmable positions and a two‑time programmable (TTP) feature that allows a second‑chance permanent setting. It offers a wide resistance range (2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), low temperature coefficient (35 ppm/°C), and ultra‑low power consumption (6 pA).\n\nIt is programmed via a 2‑wire I²C‑compatible serial interface and includes an OTP overwrite mode for temporary adjustments. The device operates from a single 2.7 V‑5.5 V supply and is rated for –40 °C to +125 °C, making it suitable for calibration, sensor adjustment, and automotive electronics applications.
