LA4743B

45W Four-Channel Bridge Circuit Power Amplifier

Overview

The is a 45 W 4-channel power amplifier IC for car stereo systems. It features a built-in bridge circuit and the ability to radically reduce the number of external components required. It is also pin compatible with the LA4743A, which differs in the amount of gain provided.

Features

• Maximum output power: 45 W ×4 channels

   VCC= 14.4 V, 4 Ω load, 1 kHz

• 40 W ×4 channels VCC= 13.7 V, 4 Ωload, 1 kHz

• Requires only seven external components and does not require an oscillation prevention RC circuit, a noise filter, or a BS capacitor.
