LP508 Datasheet (ETC) - Class A Amplifier

LP508, Class A Amplifier

The LP508 is an 8 pin Class A amplifier utilizing Gennum's proprietary low voltage bipolar JFET technology.

It consists of 2 single ended, low noise inverting gain blocks.

The first block has a typical open loop gain of 50 dB, with the closed loop gain set by the ratio of the feedback resistor to th
