GENERAL DESCRIPTION
This user guide describes the evaluation board for evaluating the
AD5246, a single channel, 128-position, digital potentiometer.
The
AD5246
supports a single-supply 2.7 V to 5.5 V operation,
making the device suited for battery-powered applications and
many other applications with a superior low temperature
coefficient performance.
In addition, the
operates in fast mode, allowing speeds of up to 400 kHz.
The
EVAL-AD5246DBZ
single-supply mode and incorporate an internal power supply
from the USB.
Complete specifications for the
the
