General Description
Features
Y
High slew rateÐ 100 V/ms
The LM715 is a high speed, high gain, monolithic operation-
al amplifier intended for use in a wide range of applications
where fast signal acquisition or wide bandwidth is required.

RingingÐExcessive ringing (long acquisition time) may oc-
cur with large capacitive loads. This may be reduced by
isolating the capacitive load with a resistance of 100X.
Large source resistances may also give rise to the same
problem and this may be decreased by the addition of a
capacitance across the feedback resistance. A value of
around 50 pF for unity gain configuration and around 3.0 pF
for gain 10 should be adequate.

Latch UpÐThis may occur when the amplifier is used as a
voltage follower. The inclusion of a diode between leads 6
and 2 with the cathode toward lead 2 is the recommended
preventive measure.

Typical Applications
Note: For gain 10, compensation may be simplified by removing C2, C3 and
adding a 200 pF capacitor (C4) between Lead 7 and 10.
