(1)

Input offset voltage drift and input bias current drift are average values calculated by taking data at the end-points, computing the

difference, and dividing by the temperature range.

(2)

Current is considered positive out of the pin. IOS = IB+ – IB–.

ΔVOS = |VOS at specified VCM – VOS at 0 V VCM|
