APPLICATIONS INFORMATION

TYPICAL OPERATING CIRCUIT

Figure 53. Typical Operating Circuit

Figure 53 shows a typical operating circuit for the AD5781

using an AD8676 for reference buffers and an AD8675 as an

output buffer. To meet the specified linearity, force sense buffers

must be used on the reference inputs. Because the output

impedance of the AD5781 is 3.4 kΩ, an output buffer is

required for driving low resistive, high capacitive loads.

EVALUATION BOARD

An evaluation board is available for the AD5781 to aid

designers in evaluating the high performance of the part with

minimum effort. The AD5781 evaluation kit includes a

populated and tested AD5781 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

AD5781. The software runs on any PC that has Microsoft®

Windows® XP (SP2) or Vista (32 bits) installed. The EVAL-

AD5781 data sheet is available, which gives full details on the

operation of the evaluation board
