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 Input voltage range of the AD8421 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 information.
5 See the Typical Performance Characteristics section for expected operation between 85°C and 125°C.
