Figure 55 shows a typical operating circuit for the AD5760

using an AD8675 as an output buffer. Because the output

impedance of the AD5760 is 3.4 kΩ, an output buffer is

required for driving low resistive, high capacitive loads.

EVALUATION BOARD

Refer to the evaluation board available for the AD5780 or

AD5790 to evaluate a 18-bit version or 20-bit version of the

AD5760. An evaluation board is available for the AD5780

to aid designers in evaluating the high performance of the part

with minimum effort. The evaluation kit includes a populated

and tested AD5780 printed circuit board (PCB). The evaluation

board interfaces to the USB port of a PC. Software is available

with the evaluation board to allow the user to easily program

the AD5780. The software runs on any PC that has Microsoft®

Windows® XP (SP2), Vista (32-bit or 64-bit), or Windows 7

installed. The UG-256 is available, which gives full details on

the operation of the evaluation board
