Functional Description

Power Supply Range

HA12173 series are provided with four line output level, which will permit on optimum overload margin
for power supply conditions. And this series are designed to operate on either single supply or split supply.

Table 1 Supply Voltage

Item HA12173 HA12174 HA12175 HA12177

Single supply 7.0 V to 16.0 V 8.0 V to 16.0 V 9.5 V to 16.0 V 12.0 V to 16.0 V
Split supply GND level ±5.0 V to 8.0 V ±5.0 V to 8.0 V ±5.0 V to 8.0 V ±6.0 V to 8.0 V

VEE level ±3.5 V to ±8.0 V ±4.0 V to 8.0 V ±4.8 V to 8.0 V ±6.0 V to 8.0 V

A. 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.

B. In case of using digital GND terminal referring to GND level, operating voltage range varies

depending on the condition at power on. On using the HA12173/174/175, use within the following
ranges to avoid latch-ups.

When power on in NR-OFF mode: ±5.0 V to ±8.0 V
When power on in NR-ON mode: ±5.7 V to ±8.0 V

C. In the reverse-voltage conditions such as ‘D-GND is higher than V

GND’, excessive current flows into the D-GND to destory this IC. To prevent such destru ctio n, pa y
attention to the followings on using.

Single power supply : Short-circuit the D-GND and GND directory on the board mounting this IC.
Split power supply : Avoid reverse conditions of D-GND and V

transient-time of power ON/OFF.

’ or ‘D-GND is lower than

CC

or VEE voltage, including

CC

Reference Voltage

For the single supply operation 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 Reference voltage are provided for the left channel and the
right channel separately. The block diagram is shown as figure 1.

Notes: 1. Voltages shown above are determined by internal circuits of LSI when take pin 20 (DGND pin) as

reference pin. On split supply use, same V
pin.

This means that it can be controlled directly by microprocessor. But power supply should be
over ±5 V, notwithstanding the prescription of table 1.

2. Each pins are on pulled down with 100 kΩ internal resistor.
Therefore, it will be low-level when each pins are open.

3. Over shoot level and under shoot level of input signal must be the standardized (High: 5.3 V,
Low: –0.2 V)

4. When connecting microcomputer or Logic-IC with HA12173 series directly, there is apprehension
of rush-current under some transition timming of raising voltage or falling voltage at V

On using, connect protective resistors of 10 to 22 kΩ to all the control pins. It is shown is test
circuit on this data sheet. And pins fixed to low level should be preferably open.

5. Pay attention not to make digital GND voltage lower than GND voltage.

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 separ 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 3.

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, Output level will be “high” when sensing no sign a l. And outp ut level will be “low” when
sensing signal.
