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

1. Each pins are on pulled down with 100 k internal 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: VCC, Low: -0.2 V)
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 external component and the REC/PB head. About these logics, please look at the Parallel Data Format.

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 k. 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.

Figure 3 PB System Level Diagram 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 k to 22 k resistor to pin 19 in series and 1 F to 22 F 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 k of pin 12. Please use resistor of 22 k on the occasion of mount.
