GENERAL DESCRIPTION
This user guide describes the evaluation board for evaluating the
—a dual-channel, 1024-position, nonvolatile memory
digital potentiometer. With versatile programmability, the AD5235
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 read-
back, and extra EEMEM for storing user-defined information,
such as memory data for other components or a lookup table.

The AD5235 supports dual-supply ±2.25 V to ±2.75 V operation
and single-supply 2.7 V to 5.5 V operation, making the device
suited for battery-powered applications and many other appli-
cations. In addition, the AD5235 uses a versatile SPI-compatible
serial interface, allowing speeds of up to 50 MHz .
