LA4508 Audio Amplifier IC (SIP-14H)

The LA4508 is a chip that has two channels for sound. It is made to fit in a package that has a part for attaching a heat sink. This package is called SIP-14H. It was made to be used in high quality sound devices like stereo systems, old radio players with tapes, speakers that have their own power and small amplifiers. It gives strong sound with very little noise and almost no sound when it starts up.

Each channel can send up to 8.5 watts of power to a speaker that uses 4 ohms when it is connected to 15 volts. This makes it a popular choice for fixing sound equipment and, for building old-style speaker systems by yourself.

Key Features

• Dual-Channel High-Efficiency Output: This product drives two speakers at the same time to produce rich stereo sound with strong dynamic range.
• Low Startup Pop Noise: It has muted-bias circuitry that stops loud popping sounds when the device is turned on or turned off.
• SIP-14H Package Design: The design uses a single-row pinout that takes up less space on the board. The integrated metal tab helps with heatsink coupling.
• Built-in Protection Circuits: It has thermal shutdown protection and overvoltage limiters to keep the chip safe under loads.
• Low Distortion Output: It gives voice and music with typical distortion levels, below 0.2% at normal listening levels.
