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
Supply Voltage Range
Product
Single Supply
HA12228F
6.5 V to 12.0 V
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.
Reference Voltage
These devices provide the reference voltage of half the supply voltage that is the signal grounds. As the
pec ulia rity of these devic es, the ca pac itor for the ripple filter is ver y small about 1/100 compa red with
their usual value. The block diagram is shown as figure 1.

Therefore, it will be low-level when each pins are open.
2. Over shoot level and under shoot level of input signal must be the standardized.

Music Sensor Time Constant
1. Sensing no signal to signal (Attack) is determined by C6, 0.01 µF to 1 µF capacitor C6 can be
applicable.
2. Sensing signal to no signal (Recovery) is determined by C6 and R11, however preceding (1), 100 kΩ
to 1 MΩ 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.
