NTE990

Integrated Circuit

Dual Audio Power Amplifier

Description:

The NTE990 is a monolithic dual power amplifier designed to deliver 2W/channel continuous into 8

Ω

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.
