| 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/s 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 be added to reduce the 0.1% setting time to under 1s. 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.
