7. Input current on AIN+ or AIN- (with Gain = 1), or VREF+ or VREF- may increase to 250 nA if operated
the differential outputs of the amplifier. In addition to the input common mode + signal requirements for
the analog input pins, the differential outputs of the amplifier must remain between (VA- + 0.1 V) and
(VA+ - 0.1 V) to avoid saturation of the output stage.
within 50 mV of VA+ or VA-. This is due to the rough charge buffer being saturated under these
conditions.
