NTE745
Description
: the NTE745 is a monolithic plementary power amplifier and preamplifier designed to deliver 1/2- Watt into a loudspeaker with a 3.0m V(rms) typical input. Gain and bandwidth are externally adjustable. Typical applications include portable AM- FM radios, tape recorders, phonographs, and inters. Features
