The AD8209A preamplifier exceeds 80 dB CMRR at 10 kHz. However, because the output is available only via the 100 kΩ resistor, even a small amount of pin to pin
capacitance between the ±IN pins and the A1 and A2 pins can couple an input common-mode signal larger than the greatly attenuated preamplifier output. The
effect of pin to pin coupling can be neglected in all applications by using a filter capacitor from Pin 3 to GND.
3
The output voltage range of the AD8209A varies depending on the load resistance and temperature. For additional information on this specification, refer to Figure 12
and Figure 13.
4
The output voltage range of A2 assumes that Pin 3 (A1 output) and Pin 4 (A2 input) are shorted together. A 25 kΩ load resistor is used for testing.
5
The output voltage range of A2 assumes Pin 4 (A2 input) is driven with an external voltage source. A 25 kΩ load resistor is used for testing.

Shunt-based applications have a low impedance shunt resistor between +IN
and −IN. See Figure 24 for an example of a shunt-based application.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
