Monolithic Linear IC
LA4815M
Monaural Power Amplifier
Overview
The LA4815M 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 surface-mounted package type with heat sink (LA4815VH).
Applications
Intercoms, door phones, transceivers, radios, toys, home appliances with voice guidance, etc.
