LA4815M
Monolithic Linear IC
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.
Features
• Built-in 1-channel power amplifier
Output power 1 = 370mW typ. (VCC = 6V, RL = 8Ω, THD = 10%)
Output power 2 = 620mW typ. (VCC = 6V, RL = 4Ω, THD = 10%)
Output power 3 = 230mW typ. (VCC = 5V, RL = 8Ω, THD = 10%)
Output power 4 = 1,000mW typ. (VCC = 12V, RL = 16Ω, THD = 10%)
• Mute function
• Selectable voltage gain : 2 types
26dB/40dB
* Gain values between 26 and 40dB can also be set by adding external components (two resistors).
• Only a few external components
4 components/total
• Wide supply voltage range
4 to 13V (When using 9V or more, another package product, LA4815VH, is recommended.)
