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–Lead SIP type package designed for use as high performance, car–audio power amplifiers in consumer applications. These
devices feature high power, low distortion, and low noise along with various types of protection circuits. The NTE1899 is a mirror image pin–out of the NTE1898 allowing for easier design of PC boards
when used in BTL–stereo applications.
