Specifications subject to change without notice. All min and max specifications are guaranteed.
Input offset voltage specifications are guaranteed after 5 minutes of operation at T
PSRR test conditions: +V
Bias Current Specifications are guaranteed maximum at either input after 5 minutes of operation at T
Gain = –1, R
Defined as voltage between inputs, such that neither exceeds ± 10 V from ground.
Typically exceeding –14.1 V negative common-mode voltage on either input results in an output phase reversal.
Open-Loop Gain is specified with V
Capacitive load drive specified for C
Refer to Table II for optimum compensation while driving a capacitive load.
