1 VCM = input common-mode voltage.

2 Source imbalance < 2 Ω.

3 The AD8209 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 neglected in all applications by using a filter capacitor from Pin 3 to GND.

4 The output voltage range of the AD8209 varies depending on the load resistance and temperature. For additional information on this specification, refer to 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 is 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 is used for testing.
