POWER SUPPLY Operating Range ±4 ±18 ±4 ±18 V Quiescent Current 6.7 7 6.7 7 mA T = 125°C 9 9 mA TEMPERATURE RANGE For Specified Performance −40 +125 −40 +125 °C 1 Total voltage noise = √(e 2 2 ni + (eno/G)2 + eRG ). 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. Rev.
