GENERAL DESCRIPTION
This user guide describes the evaluation board for evaluating the
AD5162, a dual-channel, 256-position digital potentiometer.
The
AD5162
supports a single-supply 2.7 V to 5.5 V operation,
making the device suitable for battery-powered applications and
many other applications. In addition, the
tile SPI-compatible serial interface, allowing speeds of up
to 25 MHz.
The
EVAL-AD5162SDZ
incorporates an internal power supply from the USB.
Complete specifications for the
the
AD5162
data sheet, which is available from Analog Devices,
Inc., and should be consulted in conjunction with this user
guide when using the evaluation board.
