NTE7041
Integrated Circuit Dual, Audio Power Amplifier, 22W BTL
17-Lead SIP

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:
- Low Thermal Resistance: Junction-to-Tab = 1.5°C/W (Infinite Heat Sink) - High Power: POUT(1) = 22W/Ch Typ POUT(2) = 19W/Ch Typ
- Low Distortion Ratio: THD = 0.04% Typ
- Low Noise: VNO = 0.3mVrms Typ
