Functional Description
Power Supply Range HA12228F/HA12229F are provided with three line output level, which will permit on optimum overload margin for power supply conditions. And these are designed to operate on single supply only. Table 1
Product HA12228F HA12229F Note: The lower limit of supply voltage depends on the line output reference level. The minimum value of the overload margin is specified as 12 dB by Dolby Laboratories.
Supply Voltage Range
Single Supply 6.5 V to 12.0 V
Reference Voltage These devices provide the reference voltage of half the supply voltage that is the signal grounds. As the peculiarity of these devices, the capacitor for the ripple filter is very small about 1/100 compared with their usual value. The block diagram is shown as figure 1.

Music Sensor Time Constant 1. Sensing no signal to signal (Attack) is determined by C6, 0.01 F to 1 F capacitor C6 can be applicable. 2. Sensing signal to no signal (Recovery) is determined by C6 and R11, however preceding (1), 100 k to 1 M can be applicable. Music Sensor Output (MSOUT) As for the internal circuit of music sensor block, music sensor output pin is connected to the collector of NPN type directly, therefore, output level will be "high" when sensing no signal. And output level will be "low" when sensing signal.
IL = DVCC - MSOUTLO* RL * MSOUTLO : Sensing signal (about 1V)
Note: 1. Supply voltage of MSOUT pin must be less than VCC voltage.
