GK509 Description

The GK509 is a Class A amplifier utilizing Gennum’s proprietary low voltage JFET technology. It consists of a single-ended, low noise inverting gain block, a Class A output s t a g e , a n o n - c h i p m i c r o p h o n e d e c o u p l i n g r e s i s t o r , and a pair of Schottky diodes for symmetrical peak clipping. Block A typically has an open loop voltage gain of 56 dB, with the closed loop gain set by the...
