Overview

The LA4620 is a two-channel high-power audio amplifier for automotive stereo and general-purpose audio amplification equipment.

The LA4620 has a 6 to 22V operating supply voltage range. Each channel uses a bridge configuration to obtain high output power from low supply voltages. Typical output power is 17W per channel.

The LA4620 incorporates a thermal protection circuit, an output short-circuit protection circuit and a pop suppres sion circuit. It has low-power, logic-level standby control and mute control inputs.

The LA4620 is available in 23-pin SIPs and operates from a 15V supply.
