GENERAL DESCRIPTION
This user guide describes the evaluation boards for evaluating the
AD5245, a single-channel, 256-position, I
2
C-compatible digital
potentiometer.
The AD5245 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 AD5245 uses a versatile I
2
C-compatible serial
interface that operates in fast mode, allowing speeds of up to
400 kHz. This interface can be used to read back the wiper register.
The E VA L-AD5245DBZ daughter board and the EVA L-MB-
LV-SDZ motherboard can operate in single-supply mode and
incorporate an internal power supply from the USB.
Complete specifications for the AD5245 can be found in the
AD5245 data sheet, which is available from www.analog.com
and should be consulted in conjunction with this user guide
when using the evaluation board.
