NTE NTE1830

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 contain various types of protection circuitry making them suitable for high performance car audio power
amplifier applications.
