Functional Description

Power Supply Voltage Range

HA12230NT is designed to operate on single supply, shown by table 1.

Table 1 Operating Power Supply Voltage

Item Power Supply Voltage Range

Single Supply 6.5 V to 15.0 V

Reference Voltage

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 block diagram is shown as figure 1.

Operating Mode Control

HA12230NT provide fully electronic switching circuits. And each operating mode control is controlled by
parallel data (DC voltage).

Level Diagram

The gain establishment of PB-EQ considers PB output level {(internal Line Amp. + PB Amp.) = 580 mV
(Dolby Level)} like figure 3 at the target.

After replace RA and RB with a half-fix volume, adjust level.
Regarding REC-EQ adjust the gain in front of input to this IC.
The level diagram of 1 kHz is shown figure 3.
Similarly to PB, it consider Dolby level as a stan dard. And R1 needs the value more than 5.6 kΩ.
Because mode establishment resistances are built-in, REC-EQ frequ e n cy characteristics are respectiv ely

fixed value.
In case the change of the frequency characteristics are necessary, please inquire the responsible agent

because the adjustment of resistors is necessary.

Line Mute

HA12230NT is built-in with mute circuit to Line Amp.
A mute control does with High/Low of pin 19.
Reducing pop noise is so much better 10 kΩ to 22 kΩ resistor to pin 19 in series and 1 µF to 22 µF

capacitor.
A mute is not built-in when doing a power ON/OFF.
Please correspond to it, on the side of a set system.

Test Mode

Test mode becomes if it is resistor less than 10 kΩ of pin 12.
Please use resistor of 22 kΩ on the occasion of mount.

Music Sensor Mixing Block

• Gain with TAI to MAOUT

Case of one-side input, gain with TAI to MAOUT is attenuations 6 dB.

GV = (L ⋅ R signal addition circuit) + (MS Amp. gain) + (TAI one-side input attenuations)

= 20 + 20log
≈ 24.2 (dB)

For a necessary case, please in series add CR to MAI terminal for gain regulation.
