1 Total voltage noise = √(eni2 + (eno/G)2 + eRG2). See the Theory of Operation section for more information.

2 Total RTI VOS = (VOSI) + (VOSO/G).

3 These specifications do not include the tolerance of the external gain setting resistor, RG. For G > 1, add RG errors to the specifications given in this table.

4 Differential and common-mode input impedance can be calculated from the pin impedance: ZDIFF = 2(ZPIN); ZCM = ZPIN/2.

5 Input voltage range of the AD8429 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.
