Application Note
Power Supply Range Table 1 Supply Voltage
HA12179F Single supply 6.8 V to 16.0 V
HA12179F is designed to operate on single supply. 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.

Notes: 1. Each pins are on pulled down with 100 k 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 k to 22 k resistor and 1 F to 22 F capacitor shown Fig 2. But the resistor connected to MUTE terminal (pin 16) should be under 10 k.

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.

A standard level of TAI pin is 30 mVrms and the gain for TAI to MS AMP input is 10times, therefore, the other channel sensitivity of music sensor (S) is computed by the formula mentioned below. C 1 S = 20 log [dB] 30 10 A A = MS AMP. gain (B dB) C = The sensing level of music sensor S = -7.3 - B[dB] C = 130 mVrms (typ.) S is 6 dB up in case of the both channels.

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. Supply voltage of MS OUT pin must be less than VCC voltage. 2. MS VCC pin and VCC pin are required the same voltage.
