Ordering number: EN742G Monolithic Linear IC LA4182
2.3 W 2-Channel AF Power Amplifier Package Dimensions Features . Built-in 2 channels enabling use in stereo and bridge
applications amplifier
High output: 2.3 W/channel, V = 9 V, R = 4 Ω, and
W/bridge, R = 8 Ω 4.7
Minimum number of external parts required : 9 pcs. min (Stereo/bridge).
Small pop noise at the time of power supply ON/OFF due to
muting circuit built-in
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
gain available with external resistor added voltage

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. Specifications
