NTE NTE1383 Datasheet

NTE1383

Integrated Circuit

Dual Audio Power Amp, 5.1W/Ch

(10.5W BTL)

Description:

The NTE1383 is an integrated circuit in an 18–Lead DIP designed for use as an audio output with low
noise, low distortion, and high output for a wide range of power supply voltages and load resistance.
Two built–in amplifiers provide dual or BTL operation. Typical applications include radio cassette re­corder, tape recorder, car stereo, and home entertainment.

Features:

D High Output Power, Dual or BTL Circuit Operation
D Wide Output Power Setting Range
D Wide Supply Voltage Range
D Incorporates an Automatic Operating Point Stabilizer Circuit
D Low Distortion, Low 1/f Noise, and Low Shock Noise
D High Audio Channel Separation
D Incorporates a Phase Converter
