Ordering number: EN742G Monolithic Linear IC LA4182 2.3 W 2-Channel AF Power Amplifier Features Package Dimensions unit : mm . Built-in 2 channels enabling use in stereo and bridge . amplifier applications. V = 9 V, R = 4 , and High output: 2.3 W/channel, 4.7 W/bridge, R = 8 . . Minimum number of external parts required : 9 pcs. min. . (Stereo/bridge). at the time of power supply ON/OFF due to Small pop noise muting circuit. . built-inripple rejection ratio due to built-in ripple filter. Good . 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. CC L L 3022A-DIP12F [LA4182] SANYO : DIP12F 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.
