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. |
