EVALUATION BOARD DESCRIPTION
The EVAL-AD5420 is a full-featured evaluation board, designed
to allow the user to easily evaluate all features of the AD5420
to allow the user to easily evaluate all features of the AD5420
current source, 16-bit DAC. All of the AD5420 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 AD5420 evaluation software. The
default setup is for control via the USB port.

DEVICE DESCRIPTION
The AD5420 is a low cost, precision, fully integrated 16-bit
converter, offering a programmable current source output
designed to meet the requirements of industrial process control
applications. The output current range is programmable to 4 mA
to 20 mA, 0 mA to 20 mA, or an overrange function of 0 mA to
24 mA. The output is open-circuit protected. The device is
specified to operate with a power supply range from 10.8 V to
40 V. Output loop compliance is 0 V to AV
converter, offering a programmable current source output
designed to meet the requirements of industrial process control
applications. The output current range is programmable to 4 mA
to 20 mA, 0 mA to 20 mA, or an overrange function of 0 mA to
24 mA. The output is open-circuit protected. The device is
specified to operate with a power supply range from 10.8 V to
40 V. Output loop compliance is 0 V to AV
DD
– 2.5 V.
Complete specifications for the AD5420 are available in the
data sheet available from Analog Devices, Inc., and
should be consulted in conjunction with this data sheet when
using the evaluation board.
