NTE NTE7059

NTE7059
Integrated Circuit
Dual BTL 14W Audio Power Amplifier
Description:
The NTE7059 is an integrated circuit in a 16−Lead Staggered SIP type package designed for 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 the power supply pin by applying stand−by circuit.
Features:
D High Output Power: 14W x 2
D Incorporates Protection Circuits:
Temperature, Overvoltage, VOUT−GND Short, RL Short, VOUT−VCC Short
D Low Shock Noise from Power ON/OFF Operation
D Fewer External Components
D High Stable Operation
