The LA4810M stereo/monaural BTL power amplifier is an IC that has been developed for portable radios and
compact radio cassette players/recorders containing a preamplifier, a power amplifier, and an electronic volume
control
• Audio equipment such as portable radios and compact radio cassette players/recorders
• 2-channel stereo power amplifier
• Stereo/monaural BTL selector
• Electronic volume control
• Incorporates two channels of low-voltage (V CC =1.8V or higher) drive power amplifiers
• Configurable as a monaural BTL power amplifier (selected at pin 2)
• Onchip electronic volume
• Onchip ripple filter
EIAJ output power 1=125mW typical (V CC =3V, R L =8Ω)
EIAJ output power 2=280mW typical (V CC =4.5V, R L =8Ω)
EIAJ output power 3=350mW typical (V CC =3V, R L =8Ω)
EIAJ output power 4=600mW typical (V CC =4.5V, R L =16Ω)

... It is likely that the maximum ratings of the IC may be exceeded on a slight change in operating conditions if the IC is used at or near its ratings. Since such a condition may lead to a fatal failure accident, allow for adequate margins for fluctuations in supply voltage and to make sure that the IC is used within its maximum ratings range.
