LM318

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.
