EVAL-AD5252SDZ

EVAL-AD5252SDZ is an evaluation board to evaluate the AD5252, a dual-channel, 256-position, non-volatile memory digital potentiometer. With versatile programmability, the AD5252 allows multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6dB scales, wiper setting readback, and extra EEMEM for storing user-defined information, such as memory data for other components or a lookup table. The AD5252 supports a dual-supply ±2.25V to ±2.75V operation and a single-supply 2.7V to 5.5V operation, making the device suited for battery-powered applications and many other applications. In addition, the AD5252 uses a versatile I2C serial interface that operates in fast mode, allowing speeds of up to 400kbps and supporting the selection of up to four different I2C addresses. The EVAL-AD5252SDZ can operate in single-supply and dual supply mode and incorporates an internal power supply from the USB.
