HIGH SPEED OPERATIONAL AMPLIFIER
DESCRIPTION
The UTC LM318 is a precision, high speed, high gain operational
amplifier that has been specifically designed for use in high slew rate
and wide bandwidth applications. Unlike many wideband amplifiers,
the UTC LM318 is unity-gain stable since it has internal circuitry for
frequency compensation. However, external components may be
added for compensation to achieve optimum performance.
When used in inverting applications, feed-forward compensation
can be used to achieve slew rate in excess of 150V/µs and almost
double the bandwidth. For greater stability, using overcompensation
with the amplifier is possible if maximum bandwidth is not needed. In
general, by adding a single capacitor can reduce the settling time for
0.1% error band to under 1µs.
The typical applications of UTC LM318 include A/D converters,
fast integrator, oscillators, active filters, sample and hold circuits, or
general purpose amplifiers.
