LA4815VH: Audio Power Amplifier, Class AB, 1-Channel, 1.8 W

The LA4815VH incorporates a 1-channel power amplifier with a wide operating supply voltage range built into a surface-mounted package. This IC also has a mute function and requires only a few external components, making it suitable for low-cost set design. There is also a MFP8 package type which incorporates the same chip (LA4815M).
