(1)

Total offset, referred-to-input (RTI): VOS = (VOSI) + (VOSO / G).

(2)

Specified by characterization.

(3)

Offset drifts are uncorrelated. Input-referred offset drift is calculated using: ΔVOS(RTI) = √[ΔVOSI 2 + (ΔVOSO / G)2].

(4)

Input voltage range of the Instrumentation Amplifier input stage. The input range depends on the common-mode voltage, differential

voltage, gain, and reference voltage.

(5)

The values specified for G > 1 do not include the effects of the external gain-setting resistor, RG.

(6)

Total RTI voltage noise is equal to: eN(RTI) = √[eNI 2 + (eNO / G)2].
