1 Die is specified for operation from 40°C to +150°C ( TOPR for DIE).
2 Source imbalance <2 Ω.
3 The AD8202 preamplifier exceeds 80 dB CMRR at 10 kHz. However, because 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 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 filter capacitors at Node 3.
4 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 was used for testing.
