INTRODUCTION
This data sheet describes the evaluation board for the
AD5429/AD5439/AD5449 DACs. The AD5429/AD5439/
AD5449 are CMOS 8-/10-/12-bit current output digital-to-
analog converters (DACs), respectively. They operate from a
2.5 V to 5.5 V power supply, making them suited to battery-
powered and other applications.
On power-up, the internal register and latches are filled with 0s
and the DAC outputs are at zero scale.
As a result of manufacture on a CMOS submicron process, the
parts offer excellent 4-quadrant multiplication characteristics,
with large-signal multiplying bandwidths of up to 10 MHz.

The applied external reference input voltage (V
the full-scale output current. An integrated feedback resistor
(RFB) provides temperature tracking and full-scale voltage
output when combined with an external I-to-V precision
amplifier.
The board consists of the AD5429/AD5439/AD5449 and a
current-to-voltage amplifier, AD8065. Note that, while excellent
for dc performance, the bandwidth performance of the
combined DAC and amplifier is limited to approximately
8 MHz per DAC output. Included on the evaluation board is a
10 V reference, ADR01. An external reference can also be
applied via an SMB input connector. LK1 A and LK1 B connect
the on-board reference to the V
respectively. To utilize the on-board reference, these links
should be inserted. Otherwise, they should be removed.
The evaluation kit includes a CD-ROM with self-installing
software to control the DAC. The software allows you to
exercise all functions of the AD5429/AD5439/AD5449.
Full data on the DACs is available in their respective data sheets,
which should be consulted in conjunction with this data sheet
when using the evaluation board.
