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. .
3022A-DIP12F
High output: 2.3 W/channel, VCC = 9 V, RL = 4 Ω, and 4.7 W/bridge, RL = 8 Ω. [LA4182] Minimum number of external parts required : 9 pcs. min. 12 7 (Stereo/bridge). Small pop noise at the time of power supply ON/OFF due to built-in muting circuit. 7.62 6.45 . Good ripple rejection ratio due to built-in ripple filter. 0.4 . Soft tone at the time of output saturation. 1 6 . 5.12 Good channel separation. 19.4 . Voltage gain fixed at 45 dB (Bridge: 51 dB). Variable voltage gain available with external resistor added. 3.46 . 4.26max Easy to design radiator fin. 3.5 0.51min 3.6 1.3 0.5 0.81 2.54 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.
