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 hig her than VCC' or 'D-GND is lower than GND',

excessive current flo ws 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

moun ting 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 kΩ i nternal 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.

Adjustment of Playback Dolby Level

After replace R34 and R35 with a half-fix volume of 10 kΩ, adjust RECOUT level to be Dolb y level with

playback mode.

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 an d Lch sepa r ately (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 Time Constant

• Sensing no signal to signal (Attack) is determind by C13.

0.01 µF to 1 µF capacitor C13 can be applicable.

• Sensing signal to no signal (Recovery) is determind by C13 and R24, however preceding (Attack), 100

kΩ to 1 MΩ R24 can be applicable.

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, outp ut 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.

IL=DVCC – MSOUTLo *

* MSOUTLO: Sensing signal (about 1 V)

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.
