EVALUATION BOARD DESCRIPTION
The EVAL-AD5422 is a full-featured evaluation board that is
designed to allow the user to easily evaluate all features of the
16-bit AD5422 current source and voltage output DAC. All of
the AD5422 pins are accessible at on-board connectors for external
connection. The board can be controlled by two means: via the
on-board connector (J8) or via the USB port of a Windows® 2000,
NT®, XP® based PC using the AD5422 evaluation software. The
default setup is for control via the USB port.

DEVICE DESCRIPTION
The AD5422 is a low-cost, precision, fully integrated 16-bit
converter offering a programmable current source and program-
mable voltage output designed to meet the requirements of
industrial process control applications. The output current range
can be programmed to be 4 mA to 20 mA, 0 mA to 20 mA, or an
overrange function of 0 mA to 24 mA. The voltage output is
provided from a separate pin that can be configured to provide
0 V to 5 V, 0 V to 10 V, ±5 V or ±10 V output ranges; an overrange
of 10% is available for all ranges. Analog outputs are short- and
open-circuit protected and can drive capacitive loads of 1 μF. The
device is specified to operate with a power supply range from
10.8 V to 40 V. The output loop compliance is 0 V to AV
Complete specifications for the AD5422 are available in the
