LF347 / LF353

LF347 at A500 Rev.3

Operational amplifier in the audio-circuit of the amiga. The LF347 (quad Op.A.) respective LF353 (dual Op.A.) was used in the beginning of the amiga-series and replaced often to the TL082 respective TL084.
These devices are low-cost, high-speed, JFET-input operational amplifiers. They require low supply current yet maintain a large gain-bandwidth product and a fast slew rate. In addition, their matched high-voltage JFET inputs provide very low input bias and offset current. The LF347 and LF347B can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits.
