Overview
The AD5273BRJZ10-R7, produced by Analog Devices Inc., is a 64-position, one-time programmable (OTP) digital potentiometer. This device employs fuse link technology to achieve permanent program settings, similar to the function of mechanical trimmers and variable resistors. It allows for unlimited adjustments before the resistance values are permanently set. The AD5273 is controlled using a 2-wire, I2C-compatible digital interface and supports single-supply operation from 2.7 V to 5.5 V, making it suitable for battery-powered applications and other low-power scenarios.
