To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

Functional Description
Power Supply Voltage Range
HA12230NT is designed to operate on single supply, shown by table 1.
Table 1

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.

each pins are open.
2. Over shoot level and under shoot level of input signal must be the standardized.

Block Diagram
Figure 2 shows the block diagram.
As this IC is built-in REC return switch, the configuration system can be simple system using a few

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 standard. And R1 needs the value more than 5.6 kΩ.
Because mode establishment resistances are built-in, REC-EQ frequency characteristics are respectively
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.
