HA12207NT
Audio Signal Processor for Cassette Deck
ADE-207-197B (Z) 3rd Edition Jun. 1999 Description
HA12207NT is silicon monolithic bipolar IC providing PB equalizer, REC equalizer system and each electronic control switch in one chip.
Functions
* PB equalizer * REC equalizer * REC MUTE * REC head return switch x 2 channel x 2 channel
* Each electronic control switch to change REC/PB etc.
Features
* REC equalizer is very small number of external parts, built-in 2 types of frequency characteristics. * PB equalizer circuit built-in. * REC /PB of high speed mode are possible with TYPE 1(Normal tape). * Controllable from direct micro-computer output. * Available to reduce substrate-area because of high integration and small external parts. * As the pins arrangement resembles HA12185NT, it can design the board that is replaced with HA12185NT.

Functional Description
Power Supply Range HA12207NT is designed to operate on single supply, shown by table 1. Table 1
Item Single Supply
Supply Voltage
Power Supply Range 9.5V to 15.0V
Reference Voltage As AC reference (Vref) of this IC has not a current drivability, Vref fluctuates by A/B switching of PB-EQ. Provided it causes you anxiety, please supply 7 pin with approximate 1/2 VCC voltage. 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 HA12207NT 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. Table 2

1. Each pin is pulled down with 100k internal resistor. 16 to 18 pins are low-level when each pin is open. 2. Over shoot level and under shoot level of input signal must be the standardized. (High: Less than VCC, Low: More than -0.2V)
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. As this IC adopted Hi-z SW of REC-EQ output and the input mute system, it realizes REC mute attenuation and pop-noise reduction securing in REC mute. About these logics, please look at the Parallel Data Format.

Level Block Diagram The gain establishment of PB-EQ considers PB output level {(external AMP+PB AMP)=300mV(Dolby Level)} like figure 3 as the target. Regarding REC-EQ adjust the gain in front of input to this IC. The level diagram of 1kHz is shown figure 4. (Normal speed) Similarly to PB, it consider Dolby level as a standard. And R1 needs the value more than 5.6k. 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.
