2 The AD8203 preamplifier exceeds 80 dB CMRR at 10 kHz. However, since 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 may couple an input common-mode signal larger than the greatly attenuated preamplifier output. The effect of pin-
to-pin coupling may be neglected in all applications by using filter capacitors at Node 3.
3 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 used for testing.
