NTE990
Integrated Circuit
Dual Audio Power Amplifier
Description:
The NTE990 is a monolithic dual power amplifier designed to deliver 2W/channel continuous into 8
loads. The NTE990 is designed to operate with a low number of external components, and still pro-
vide flexibility for use in stereo phonographs, tape records and AM–FM stereo receivers, etc. Each
power amplifier is biased from a common internal regulator to provide high power supply rejection,
and output Q point centering. The NTE990 is internally compensated for all gains greater than 10.
