GENERAL DESCRIPTION

The Analog Devices, Inc., 8-lead SOIC evaluation board for
differential drivers is designed to help users evaluate differential
drivers offered in 8-lead standard small outline (SOIC) packages.
The 8-lead SOIC differential driver evaluation board makes it
easy for designers to obtain quick performance results for their
specific differential driver application circuits.

Evaluation Board User Guide

The 8-lead SOIC evaluation board is a bare board (that is, no
components are soldered to the board) that enables users to
quickly prototype a variety of differential driver circuits, thereby
minimizing risk and reducing time to market. The board layout
is very flexible and allows for many circuit configurations, includ-
ing traditional four-resistor circuits, circuits with two different
feedback loops, filters, and many others. Most resistors and
capacitors use 1206, 0402, 0508, and 0603 packages.
Figure 1 shows the component side of the bare evaluation board,
and Figure 2 shows the circuit side of the evaluation board.
Because this universal evaluation board can be used with many
Analog Devices differential amplifiers in 8-lead SOIC packages,
the evaluation board label does not contain specific part numbers.
The board accommodates the ADA4940-1, as well as many
members of the
AD813x
family of differential amplifiers (see the
Related Links section). The data sheets for these devices should
be consulted in conjunction with this evaluation board user guide.
