Input Capacitance
The parallel-connected differential input stages for rail-to-rail operation results in relatively large input capacitance C
(6pF typ). This introduces a pole at frequency (2
resistors for the inverting or non-inverting amplifier configuration
parable to the unity-gain bandwidth (10MHz), the phase margin is reduced, and the amplifier exhibits degraded AC
performance through either ringing in the step response or sustained oscillations.
