NTE7113
Integrated Circuit
Dual Audio Power Amplifier, 14W BTL
Description:
The NTE7113 is an integrated circuit in a 16−Lead Staggered SIP type package designed for use as
a 14W (13.2V, 4Ω) output power amplifier. Stereo operation is enabled due to incorporating two BTL
amplifiers. High reliability is obtained due to incorporating protectors. ON/OFF is enabled even if
power is supplied to power supply terminal by applying stand−by circuit.
