Pin No. Pin name Function DC voltage Equivalent circuit 30 31 42 43 AOUT2L AOUT2R AOUT3L AOUT3R Audio output terminal Push-pull output Low-Impedance 4.91V 39 40 AOUT1L AOUT1R Audio output terminal Push-pull output Low-Impedance 4.91V 41 44 PWRMUTE1 PWRMUTE2 Output terminal of audio muting 0V Power Save LA73024AV has two supplies 5V for Video part and 12V for audio part and FSS output. LA73024AV separates perfectly 5V system from 12V system, so it can be individually movement. For example when in the stand-by mode, if you open 14 pins but 5V supplies 24 and 29 pins, Video part and serial control part work normally. In this case audio part and FSS output don’t work normally. And when you pull up 8pin and open 24 pin , IC chooses automatically video sw3-B.Consequently Ext input and Decoder output only move , you can save more power dissipation . Audio Mute LA73024AV builds in two mute transistors for reduce audio pop-noise when occur at power on and off. You can control both on serial control and on external parallel control for audio mute.
