pole at frequency (2
πR′CIN)-1, where R′ is the parallel
combination of the gain-setting resistors for the invert-
ing or noninverting amplifier configuration (Figure 2). If
the pole frequency is less than or comparable to the
unity-gain bandwidth (10MHz), the phase margin will
be reduced, and the amplifier will exhibit degraded
AC performance through either ringing in the step
response or sustained oscillations. The pole frequency is
10MHz when R
′ = 3.2k. To maximize stability, R′ <3k
is recommended.
Applications that require rail-to-rail operation with mini-
mal loading (for small VDD - VOH and VOL - VSS) will
typically require R
′ values >3k. To improve step
response under these conditions, connect a small
capacitor Cf between the inverting input and output.
Choose Cf as follows:
Cf = 5(R / Rf) [pf]
where Rf is the feedback resistor and R is the gain-set-
ting resistor (Figure 2).
Figure 3 shows the step response for a noninverting
amplifier subject to R
′ = 4k with and without the Cf
feedback capacitor.
