See the AD8421 data sheet 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-EP input stage only. The input range can depend on the common-mode voltage, differential voltage, gain, and reference voltage. See the Typical Performance Characteristics section for more information.
