This datasheet describes the AD5272/AD5274 single-channel digital potentiometers with 1024/256-bit resolution, I2C interface, and 50-TP memory.
The AD5272/AD5274 are single-channel digital potentiometers that combine advanced variable resistor performance with nonvolatile memory (NVM) in a compact package. These devices offer an end-to-end resistance tolerance error of less than 1% and provide 50 times programmable (50-TP) memory. The industry-leading guaranteed low resistance tolerance error simplifies open-loop applications, as well as precision calibration and tolerance-matching applications. This manual is written in Chinese.
