evaluation board for evaluating theAD5254—a quad-channel, 256-position, nonvolatile memory digital potentiometer. With versatile programmability, the AD5254 allows multiple modes of operation, including read/write access in the RDAC and EEMEM registers, increment/decrement of resistance, resistance changes in ±6 dB scales, wiper setting readback, and extra EEMEM for storing user-defined information, such as memory data for other components or a lookup table. The AD5254 supports a dual-supply ±2.25 V to ±2.75 V operation and a single-supply 2.7 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications. In addition, the AD5254 uses a versatile I2C serial interface that operates in fast mode, allowing speeds of up to 400 kbps and supporting the selection of up to four different I2C addresses. The EVAL-AD5254SDZ can operate in single-supply and dualsupply mode and incorporates an internal power supply from the USB.
