LA4182 Datasheet, PDF (1/9 Pages) Sanyo Semicon Device – 2.3 W 2-Channel AF Power Amplifier
Ordering number: EN742G
Monolithic Linear IC
LA4182
2.3 W 2-Channel AF Power Amplifier
Features
. Built-in 2 channels enabling use in stereo and bridge
. amplifier applications.
High output: 2.3 W/channel, VCC = 9 V, RL = 4 Ω, and
. 4.7 W/bridge, RL = 8 Ω.
Minimum number of external parts required : 9 pcs. min.
. (Stereo/bridge).
Small pop noise at the time of power supply ON/OFF due to
built-in muting circuit.
. Good ripple rejection ratio due to built-in ripple filter.
. Soft tone at the time of output saturation.
. Good channel separation.
. Voltage gain fixed at 45 dB (Bridge: 51 dB). Variable
. voltage gain available with external resistor added.
Easy to design radiator fin.

Specifications
Note) In general applications, heat generated in this package
can be radiated through the Cu-foiled area of the printed
circuit board, but since power dissipation Pd may be
increased depending on the supply voltage and load
conditions, it is recommended to use a fin additionally.
