... LA4815VH Overview 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). ...

... Using the smallest resistor Rg1 value possible is recommended. In addition, when setting the signal level, the voltage gain should be set on the LA4815VH side and the input front-end should be configured using only the input coupling capacitor, Cin, as shown in Fig order to maximize the ripple rejection ratio ...

... The internal power amplifier circuit can be disabled and audio mute is turned on by controlling the voltage applied to Pin 3. Control can be performed directly using the CPU output port, but digital noise from the CPU may worsen the LA4815VH noise floor. Therefore, inserting a series resistor, Rm1 (1 to 2.2kΩ) as shown in Fig recommended. • Mute ON : Low • ...

... Locate this bypass capacitor as close to the IC as possible. 10. NC pin treatment Since the NC pins (pins 5 to 10) are connected to nothing internally, they may be left open. To increase the heat dissipation efficiency, however recommended that the NC pins should be connected to the GND line. LA4815VH LA4815VH Cmt 1μ ...
