AD5171BRJZ100-R2 AD5171BRJZ100-R2 – 64-Position, 100kΩ OTP Digital Potentiometer

AD5171BRJZ100-R2  Overview

The AD5171BRJZ100-R2 from Analog Devices (now part of TI) is a 64-position, one-time programmable (OTP) digital potentiometer designed for set-and-forget resistance settings. It replaces mechanical trimmers with a fuse-based memory solution, ensuring permanent resistance retention without the need for reprogramming. With an I2C-compatible interface, ultra-low power consumption, and a compact SOT-23-8 package, it is ideal for precision adjustments in industrial, automotive, and consumer applications.

Key Features

✅ One-Time Programmable (OTP): Fuse-link technology locks resistance permanently after final adjustment.
✅ Wide Resistance Range: 100kΩ end-to-end resistance with ±30% tolerance.
✅ I2C Interface: Simple 2-wire control with selectable address (AD0 pin) for multi-device configurations.
✅ Low Tempco: 35 ppm/°C in rheostat mode, ensuring stability across temperatures.
✅ Compact Design: 8-lead SOT-23 package for space-constrained applications.
