NTE1830 & NTE1831
Integrated Circuit
Dual Audio Power Amplifier, 5.8W (19W BTL)
Description:
The NTE1830 and NTE1830 are dual audio power amplifiers in a 12–Lead DIP type package for use
in consumer applications. Designed for high power, low distortion, and low noise, these devices con-
tain various types of protection circuitry making them suitable for high performance car audio power
amplifier applications.
