General Purpose Amplifier 1 Circuit 8-SOIC

LM318D General Description

Designed for precision and speed, the LM318D operational amplifier is suited for wide bandwidth and high slew rate applications. Delivering a substantial speed increase compared to general-purpose devices, it maintains excellent dc precision. Its internal unity-gain frequency compensation simplifies operation, with the option of adding external frequency compensation for enhanced performance. In inverting applications, feed-forward compensation raises the slew rate to over 150 V/µs and nearly doubles the bandwidth. Overcompensation can also be utilized for increased stability, while the addition of a single capacitor reduces settling time for 0.1% error band to under 1 µs. These features make the LM318D ideal for A/D converters, oscillators, active filters, sample-and-hold circuits, and general-purpose amplifiers
