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: (TA = +25°C unless otherwise specified)
