NTE7163 Intergrated Circut 4 x 40W Quad Bridge Car Radio Amplifier
Description: The NTE7163 is a new technology class AB audio power amplifier in a 25-Lead Staggered SIP type package designed for high end car radio applications. Thanks to the PNP/NPN output configuration the NTE7163 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets. Features: D High Output Power Capability 4 x 45W/4 Max 4 x 40W/4 J 4 x 28W/4 @ 14.4V, 1KHz, 10% 4 x 24W/4 @ 13.2V, 1KHz, 10% D Low Distortion D Low Output Noise D ST-BY Function D Mute Function D Automute at Min.
