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 LA4743B, which differs in the amount of gain provided.
Features
• Maximum output power: 45 W ×4 channels
VCC= 14.4 V, 4 Ωload, 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.
