3022A-DIP12F
High-output: 2.3 W typ./channel, VCC = 9 V, RL = 4 Ω [LA4183] 4.7 W typ./bridge amplifier, V 12 7 CC = 9 V, RL = 8 Ω . Low switching distortion at high frequencies. Minimum number of external parts required: 9 pcs. min. 7.62 6.45 (Stereo/bridge). 0.4 Small shock noise at the time of power supply ON/OFF due 1 6 5.12 19.4 to built-in muting circuit. Good ripple rejection due to built-in ripple filter. 3.46 Soft tone at the time of output saturation. 4.26max Good channel separation. 3.5 0.51min Voltage gain fixed at 45 dB (Bridge: 51 dB). 3.6 1.3 0.5 Variable voltage gain available with external resistor added. 0.81 2.54 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.
