NTE7041
Integrated Circuit
Dual, Audio Power Amplifier, 22W BTL
Description:
The NTE7041 is an integrated circuit in a 17–Lead SIP type package designed for stereo audio use
in car stereo applications. This device has two built–in channels to reduce the characteristic difference between L and R channels. In addition, the NTE7041 contains stand–by and muting functions
and includes a variety of protection circuits.
Features:
D Low Thermal Resistance: Junction–to–Tab = 1.5°C/W (Infinite Heat Sink)
D High Power: POUT(1) = 22W/Ch Typ
POUT(2) = 19W/Ch Typ
D Low Distortion Ratio: THD = 0.04% Typ
D Low Noise: VNO = 0.3mVrms Typ
D Built–In Stand–By Function: ISB = 1µA Typ
D Built–In Muting Function: V(Mute) = 1V Typ
