Description
The KT2001 Point Source Processing Circuit provides a compact way to implement a point source speaker
system. It is designed to operate with either a dual supplies or a single supply voltage; an internal reference
voltage source generates a reference at half of the supply voltage. The chip is fabricated with a bipolar
process that yields low noise while allowing a wide supply voltage range (5V to 12V).
