electronic control switch in one chip.

Functions

• PB equalizer × 2 channel

• REC equalizer × 2 channel

• Each electronic control switch to change REC/PB etc.

• REC head return switch

Features

• REC equalizer is very small number of extern al parts, built-in 2 types of frequency characteristics.

• PB equalizer circuit built-in.

• REC /PB are possible with TYPE I/II.

• Controllable from direct micro-computer output.

• Available to reduce substrate-area because of high integration and small external parts.

Functional Description

Power Supply Range

HA12219NT is designed to operate on single supply, shown by table 1.

Table 1 Supply Voltage

Item Power Supply Range

Single Supply 9.5 V to 15.0 V

Reference Voltage

As AC reference (Vref) of this IC has not a curr ent drivability, Vref fluctuates by A/B switching of PB-EQ.
Provided it causes you anxiety, please supply 7 pin with approximate 1/2 V
For example, a suitable circuit is shown by figure 1.
This IC has a capacitor charger for the Vref, indicated to the pin interface circuit figure.

Operating Mode Control

HA12219NT provides fully electronic switching circuits. And each operating mode control is controlled
by parallel data (DC voltage).

Table 2 shows the control voltage of each control input pin.

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 Block Diagram

The gain establishment of PB-EQ considers PB output level
{(external AMP+PB AMP <HA12136A>) = 580 mV (Dolby Level)} like figure 3 as the target.

Regarding REC-EQ adjust the gain in front of input to this IC.
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.
