HA12173 Series

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 VCC’ or ‘D-GND is lower than GND’ ,

excessive current flows into the D-GND to destory this IC. To prevent such destruction, pay 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 VCC or VEE voltage, including

transient-time of power ON/OFF.

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 VTH can be offered by connecting DGND pin to GND 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 VCC ON/OFF.

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.
