The AD8202 preamplifier exceeds 80 dB CMRR at 10 kHz. However, because the signal is available only by way of a 100 kΩ resistor, even the small amount of pin-to-
pin capacitance between Pin 1, Pin 8 and Pin 3, Pin 4 might 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 filter capacitors at Node 3.
