The AD5170 is a 256-position two-time programmable I2C digital potentiometer, which offers four end-to-end resistance selections of 2.5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ.
The AD5170 is a 256-position, two-time programmable (TTP) digital potentiometer that employs fuse link technology. It offers unlimited adjustments prior to one-time programming (OTP) activation and allows for dynamic adjustments even after the OTP setting has been permanently set via an overwrite feature.
The device features end-to-end resistance options of 2.5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ in a compact 10-lead MSOP package. It operates with a single supply voltage ranging from 2.7 V to 5.5 V and includes features such as fast settling time (typical 5 µs) and low power consumption.
