GENERAL DESCRIPTION
This data sheet describes the evaluation board for the
AD5444/AD5446 DACs. The AD5444/AD5446 are, respect-
ively, CMOS 12-/14-bit current output, digital-to-analog
converters (DACs). They operate from a +2.5 V to +5.5 V
power supply, making them suited to battery-powered and
other applications.
These DACs use data readback, allowing the user to read the
contents of the DAC register via the DB pins. On power-up, the
internal register and latches are filled with zeros and the DAC
output is at zero scale.
Because the DACs are manufactured on a CMOS submicron
process, they offer excellent four-quadrant multiplication
characteristics.

Complete information about the DAC can be found in the
AD5444/AD5446 data sheet that is available from Analog
Devices, Inc.; it should be consulted in conjunction with this data
sheet when using the evaluation board.
PACKAGE CONTENTS
The board consists of the AD5444/AD5446 and a current-to-
voltage amplifier (AD8065). Included on the evaluation board is
a 10 V reference (ADR01). Also, an external reference can be
applied via an SMB input connector, and the SDO readback
function can be enabled. The LDAC function is not available
with the AD5444/AD5446.
Included in the evaluation kit is a CD ROM with self-installing
software to control the DAC. The software allows the user to
exercise all functions of the AD5444/AD5446.
