NTE1898 & NTE1899
Integrated Circuit
Dual Audio Power Amp, 5.8W (22W BTL)
Description:
The NTE1898 and NTE1899 are dual audio power amplifiers in a 12鈥揕ead SIP type package de-
signed for use as high performance, car鈥揳udio power amplifiers in consumer applications. These
devices feature high power, low distortion, and low noise along with various types of protection cir-
cuits. The NTE1899 is a mirror image pin鈥搊ut of the NTE1898 allowing for easier design of PC boards
when used in BTL鈥搒tereo applications.
