GENERAL DESCRIPTION
This user guide describes the evaluation board for evaluating
the AD5270 and AD5272 digital rheostats. These devices are a
single-channel, 1024-position digital rheostat with less than ±1%
end-to-end resistor tolerance error and 50-time programmable
memory.
The AD5270 and AD5272 support a dual-supply ±2.5 V to ±2.75 V
operation and a single-supply 2.7 V to 5.5 V operation, making
them suited for battery-powered applications and many other
applications.
The AD5270 uses a versatile 3-wire serial interface that operates
at clock rates up to 50 MHz, and it is compatible with standard
SPI, QSPI™, MICROWIRE™, and DSP interface standards.
The AD5272 uses a versatile I
2
C serial interface that operates in
fast mode, allowing speed until 400 kbps. The device allows the
selection of up to three different I
2
C addresses.
The EVAL-AD527xSDZ evaluation board can operate in single-
supply and dual-supply mode and incorporates an internal power
supply from the USB.
Complete specifications for the AD5270 and AD5272 parts can
be found in their datasheets, which are available from Analog
Devices, Inc., and should be consulted in conjunction with this
user guide when using the evaluation board.
