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. Rev.
