EVALUATION BOARD FOR THE DAC
The evaluation board consists of an AD5450, AD5451, A
or AD5453 DAC and a current-to-voltage amplifier, such as
AD8065. Included on the evaluation board is a 10 V reference,
ADR01. An external reference can also be applied via an SMB
input.
The evaluation kit consists of a CD with PC software to control
the DAC. The software allows the user to write code to the device.

POWER SUPPLIES FOR THE EVALUATION BOARD
The board requires ±12 V and +5 V supplies. The +12 V V
and −12 V V
is used to power the DAC (V
Both supplies are decoupled to their respective ground plane
with 10 μF tantalum and 0.1 μF ceramic capacitors.
