Description
The AD5252BRUZ1 is a dual 256-position digital potentiometer from Analog Devices, designed for industrial, automotive, and instrumentation applications. It features nonvolatile memory that stores the wiper setting with write protection, allowing for power-on refreshed settings in 300 microseconds typically. The device has a resistance tolerance stored in nonvolatile memory and 12 extra bytes for user-defined information. It also offers direct read/write access to RDAC and EEMEM registers via an I2C-compatible serial interface. This digital potentiometer is commonly used in applications such as sensor calibration, gain/offset adjustment, volume control, and calibration purposes in various industries.
