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 provide flexibility for use in stereo phonographs, tape records and AMFM 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.
