| NTE1373 Integrated Circuit Dual Audio Power Amplifier Circuit, 7.5W Description: The NTE1373 is an integrated circuit designed for use as a 7.5W (16W, 4) power amplifier output with low noise and low distortion suitable for TV sets with multi-sound. Stereo operation is possible due to incorporating two amplifiers on one 12-Lead SIP type chip. Features: D Built-In Protection Circuits (Surge, Thermal Protection, etc.) D Automatic Operating Point Stabilizer Circuit D Low Distortion, Low 1/f Noise D Low Shock Noise from Power ON/OFF Operation D Better Channel Separation D Few External Components Required Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Supply Voltage, VCC Note 1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 24V Note 2 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20V Supply Current, ICC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4A Power Dissipation (TA = +45C), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30W Operating Ambient Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -30 to +75C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +150C Note 1.
