Overview
The LA4742 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.
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.
