Please consult to HITACHI sales engineers when it will use the split supply. 1. 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. 2. In the reverse-voltage conditions such as 'D-GND is higher than VCC' or 'D-GND is lower than GND', excessive current flows into the D-GND to destroy this IC. To prevent such destruction, pay attention to the followings on using.Therefore, Short-circuit the D-GND and GND directory on the board mounting this IC. Reference Voltage For the single supply operation this device provides 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 Reference voltage are provided for the left channel and the right channel separately. The block diagram is shown as figure 1. 22 47 VCC – L channel reference + 30 MS VREF – Music sensor reference R channel reference + – GND 49 50 VREF (L) + 40 + RIP C22 1µ 52 VREF (R) Figure 1 The Block Diagram of Reference Voltage Supply Rev.1, Apr. 1994, page 10 of 40 HA12179F Operating Mode Control HA12179F provides electronic switching circuits. And each operating mode control are controlled by parallel data (DC voltage).

Each pins are on pulled down with 100 kΩ internal resistor. 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 (High: 5.3 V, Low: –0.2 V) 3. Reducing pop noise is so much better for 10 kΩ to 22 kΩ resistor and 1 µF to 22 µF capacitor shown Fig 2. But the resistor connected to MUTE terminal (pin 16) should be under 10 kΩ.

Note on Connecting with Tape Head to IC This IC has no internal resistor to give the DC bias current to equalizer amp., therefore the DC bias current will give through the head. This IC provides the Vref buffer output pin for Rch and Lch separately (has two Vref terminal). In case of use that the Rch and Lch reference of head are connected commonly, please use one of Vref terminals of IC (47 pin or 52 pin) for head reference. If both 47 pin and 52 pin of IC are connected, rush current give the great damage to IC. The application circuit is shown in figure 4.

Music Sensor Output (MS OUT) As for the internal circuit of music sensor block, music sensor out 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. Connection with microcomputer, design IL at 1mA typ. DVCC – MSOUTLo * RL * MSOUTLO: Sensing signal (about 1 V) IL = Notes: 1.
