NJM318
HIGH-SPEED OPERATIONAL AMPLIFIER
■
GENERAL DESCRIPTION
■
PACKAGE OUTLINE
The NJM318 is a precision high-speed operational amplifier, which
designed for applications requiring wide bandwidth and high slew rate.
They feature a factor of ten increases in speed over general purpose
devices without sacrificing DC performance.
The NJM318 has internal unity gain frequency compensation. This
considerably simplifies its application since no external components are
NJM318D
necessary for operation. However, unlike most internally compensated
amplifiers, external frequency compensation may be added for optimum
performance. For inverting applications, feedforward compensation will
boost the slew rate to over 150V/µs and almost double the bandwidth.
Overcompensation can be used with the amplifier for greater stability
when maximum bandwidth is not needed. Further, a single capacitor can
NJM318E
be added to reduce the 0.1% setting time to under 1µs.
The high speed and fast setting time of these op amps make them
useful in A/D converters, oscillators, active filters, sample and hold
circuits, or general purpose amplifiers. These devices are easy to apply
and offer an order of magnitude better AC performance than industry
standards such as the NJM741.
