The AD8208 preamplifier exceeds 80 dB CMRR at 10 kHz. However, because the output is available only by way of the 100 kΩ resistor, even a small amount of pin-to-
pin capacitance between the IN pins and the A1 and A2 pins might couple an input common-mode signal larger than the greatly attenuated preamplifier output. The
effect of pin-to-pin coupling can be negated in all applications by using a filter capacitor from Pin 3 to GND.
4
The output voltage range of the AD8208 varies depending on the load resistance and temperature. For additional information on this specification, see Figure 12 and Figure 13.
5
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.
6
The output voltage range of A2 assumes Pin 4 (A2 Input) is driven with an external voltage source. A 25 kΩ load resistor was used for testing.
