is only used to cut noise bandwidth, a similar effect
can be achieved using the over-compensation terminal.
The Gain, Phase plot also shows that phase margin is
about 45
°
at gain of 10 (20dB). The following configura-
tion has a high (
70%) overshoot without the 10pF
capacitor because of additional phase shift caused by the
feedback resistor – input capacitance pole. The presence
of the 10pF capacitor cancels this pole and reduces
overshoot to 5%.
Over-Compensation
The LT1028/LT1128 are equipped with a frequency over-
compensation terminal (pin 5). A capacitor connected
between pin 5 and the output will reduce noise bandwidth.
Details are shown on the Slew Rate, Gain-Bandwidth
Product vs Over-Compensation Capacitor plot. An addi-
tional benefit is increased capacitive load handling capa-
bility.
