Digital Potentiometer
GENERAL DESCRIPTION
This user guide describes the evaluation boards for evaluating the
AD5165, a single-channel, 256-position, ultralow power, 1.8 V
logic level digital potentiometer.
The
AD5165
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
AD5165
to vary the wiper setting. The resistance between the wiper and
either end point of the fixed resistor varies linearly with respect to
the digital code transferred into the RDAC latch.
The
EVAL-AD5165DBZ
LV-SDZ motherboard can operate in single-supply mode and
incorporate an internal power supply from the USB.
Complete specifications for the
AD5165
data sheet, which is available from
and should be consulted in conjunction with this user guide
when using the evaluation board.
