TYPICAL OPERATING CIRCUIT
Figure 55 shows a typical operating circuit for the
using an
output buffer. To meet the specified linearity, force sense buffers
must be used on the reference inputs. Because the output

EVALUATION BOARD
An evaluation board is available for the
designers in evaluating the high performance of the part with
minimum effort. The
populated and tested
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-
