GENERAL DESCRIPTION

This user guide describes the evaluation boards for evaluating the
AD5161, a 256-position SPI-/I
The AD5161 supports single-supply 2.7 V to 5.5 V operation,
making the device suitable for battery-powered applications and
many applications requiring superior low temperature coefficient
performance.
In addition, the AD5161
compatible digital interface, which can be used to control the
wiper settings or to read back the wiper register content. In SPI
mode, the device can be daisy-chained (SDO to SDI), allowing
several parts to share the same control lines. In I
Address Pin AD0 can be used to place up to two devices on the
same bus. In this same mode, command bits are available to reset
the wiper position to midscale or to shut down the device into a
state of zero power consumption.
The EVAL-AD5161DBZ
LV-SDZ motherboard can operate in single-supply mode and
incorporate an internal power supply from the USB.
Complete specifications for the
AD5161 data sheet, which is available from
