See the Theory of Operation section for more information. 2 These specifications do not include the tolerance of the external gain setting resistor, RG. For G>1, RG errors should be added to the specifications given in this table. 3 Differential and common-mode input impedance can be calculated from the pin impedance: ZDIFF = 2(ZPIN); ZCM = ZPIN/2. 4 Input voltage range of the AD8229 input stage only. The input range can depend on the common-mode voltage, differential voltage, gain, and reference voltage. See the Input Voltage Range section for more details. 5 For the guaranteed operation time at the maximum specified temperature, refer to the Predicted Lifetime vs. Operating Temperature section. Rev.
