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.
