Evaluation Board for the AD623
AD623-EVALZ
offset voltage, apply an output reference, or provide shield
drivers with user-supplied components. The board is shipped
with a surface-mount package installed, and it has an alternative
footprint for a through-hole, 8-lead PDIP.
FEATURES
Accepts SOIC or PDIP packages
Configurable for dual or single supplies
Provision for optional circuitry
Shield driver
BASIC OPERATION
Adjustable offset/reference
The AD623 converts a differential signal to a single-ended signal
with respect to a reference. User-supplied power supplies
connect +VS, –VS, and ground to pins of the AD623 on the
evaluation board. The differential signal is applied to the +IN
and –IN pins of the AD623, and the output is monitored at the
in-amp’s OUTPUT pin. Figure 2 shows the component layout
and location of connections.
GENERAL DESCRIPTION
The AD623-EVALZ is an easy-to-use accessory for evaluating
the AD623 instrumentation amplifier. In addition to the basic
in-amp connection, circuit options enable the user to adjust the
