1 / 11 page 2.3 W 2-Channel AF Power Amplifier for Radio Cassette Players Features . Built-in 2 channels enabling use in stereo and bridge amplifier (BTL) applications. . High-output: 2.3 W typ./channel, VCC =9 V, RL =4 Ω 4.7 W typ./bridge amplifier, VCC =9 V, RL =8 Ω . Low switching distortion at high frequencies. . Minimum number of external parts required: 9 pcs. min. (Stereo/bridge). . Small shock noise at the time of power supply ON/OFF due to built-in muting circuit. . Good ripple rejection 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. Package Dimensions unit : mm 3022A-DIP12F [LA4183] SANYO : DIP12F Note: In general applications, heat generated in the DIP 12-pin 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.
