NTE1232
Integrated Circuit
Audio Amplifier for Car Radio, 8W
Description:
The NTE1232 is a Class B audio amplifier in a 5–Lead TO220 type package designed for driving low
impedance loads (down to 1.6
). This device provides a high output current capability (up to 3.5A),
very low harmonic and cross–over distortion.
