Integrated Circuit
Dual Audio Power Amplifier Circuit, 7.5W
Description:
The NTE1373 is an integrated circuit designed for use as a 7.5W (16W, 4Ω) 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: (T_A = +25°C unless otherwise specified)
