GENERAL DESCRIPTION
This user guide describes the evaluation boards for evaluating the
AD5232, a single-channel, 256-position, SPI-compatible digital
potentiometer.
The AD5232 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 AD5232 uses a versatile SPI-compatible serial
interface that operates in fast mode, allowing speeds of up to
50 MHz. This interface can be used to read back the wiper register.
The E VAL -AD5232DBZ daughter board and the E VAL -MB-
LV-SDZ motherboard can operate in single-supply mode and
incorporate an internal power supply from the USB.
Complete specifications for the AD5232 can be found in the
AD5232 data sheet, which is available from www.analog.com
and should be consulted in conjunction with this user guide
when using the evaluation board.
