GENERAL DESCRIPTION
The AD8220-EVAL offers users the option of evaluating the
AD8220 by itself or within the context of an application. The
evaluation board is arranged such that users can easily adjust
the gain resistor and reference jumper. The board offers an
SMA/SMB outline at the output. Users can add their own
connector to interface the board with complementary tools
such as an analog-to-digital converter (ADC) evaluation board,
available from Analog Devices, Inc. Breadboard space has been
integrated to promote experimentation with the AD8220. For
example, active filters, line drivers, and converters can be placed
on the breadboard space, extending the use of the evaluation
board as a development tool.

W1 is soldered
QUICK START
Connect a ±2.3 V to ±15 V supply to +V
inputs with a signal. Measure the output on a multimeter or
oscilloscope. The output voltage is the voltage measured
between OUT and REF. The output can drive another device,
such as an ADC.

REFERENCE
The instrumentation amplifier’s reference level can be set by
driving the REF pin with a precision voltage reference or by
using the solder jumper, W1. By default, W1 is soldered, shunting
REF to GND. If a reference voltage other than ground is used,
the solder must be removed from W1 before driving REF with
the reference voltage, as shown in Figure 2.

... ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8220-EVAL features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...
