HA12206NT
Audio Signal Processor for Cassette Deck
ADE-207-198B (Z)
3rd Edition
Jun. 1999
Description
HA12206NT is silicon monolithic bipolar IC providing music sensor system, ALC, REC equalizer system
and each electronic control switch in one chip.
Functions
• REC equalizer
× 2 channel
• Line Amp.
× 2 channel
• ALC (Automatic Level Control)
• MS (Music Sensor)
• Each electronic control switch to change REC equalizer, bias, etc.
• REC mute
Features
• REC equalizer is very small number of external parts, built-in 2 types of frequency characteristics.
• Correspondence with normal position (TYPE I) / high position (TYPE II).
• TYPE I / TYPE II and PB equalizer fully electronic control switching built-in.
• Controllable from direct micro-computer output.
• Available to reduce substrate-area because of high integration and small external parts.

Note: HA12206NT is designed to operate on split supply.
As VEE pin is joined the substrate of chip, there is the possibility of latch-up in such case that the other pin is
supplied a voltage and VEE pin is open.
Therefore please use as VEE pin become the lowest voltage of low impedance all the time. When power
supply is thrown into this IC, that caution is necessary especially.
Operating Mode Control
HA12206NT provides fully electronic switching circuits. And each operating mode control is controlled by
parallel data (DC voltage).

PB Equalizer
By switching logical input level of pin17 (for Ain) or pin18 (for Bin), you can equalize corresponding to
tape position at play back mode.
Frequency characteristics of high position (TYPE II) depends on capacitor C1 on the block diagram figure.
Figure 1 is shown by a motive of the NAB standard.

Figure 3 Frequency Characteristic of MS AMP
Occasion of the external component of figure 2, f1 is 430Hz and f2 is 1.1kHz.
As the MS sensitivity is prescribed at 5kHz, this stage’s gain is 7.9dB. But in only one-sided channel input
case, this gain is considered as –6dB down, because the other channel input pin is imaginary earth. That is,
the gain from RPOUT to MSDET is 1.86dB.
As the detection sensitivity at MSDET is fixed 130mVrms, the sensitivity at RPOUT (8 pin or 23 pin) is
calculated by the following formula.
130mV = 105mV
1.86
20

Because of RPOUT=580mVrms=0dB, therefore, the MS sensitivity becomes –14.8dB.
That is the detection level.

Like the figure 4 (2), Recovery time is variably possible by value of resistor R6. But Attack time gets about
fixed value. Attack time has dependence by input level. When a large signal is inputted, Attack time is
short tendency.

Music Sensor Output (MSOUT)
Because MS out pin is connected to the collector of NPN type directly, it is requested to use pull up resistor
(RL=10k to 22kΩ)
Output level is “High” sensing no signal. And output level is “Low” sensing signal.
Please take notice of MS Low level voltage (GND+0.9V).
The connected supply voltage must be less than VCC voltage, with MSOUT pull up resistor.
Automatic Level Control (ALC)
RPOUT
ALC is the input decay rate variable system.
It has internal variable resistors of pin6 (pin25) by RECOUT signal that is inputted to pin8 (pin23).
The operation is similitude to MS, detected by pin15.
The signal input pin is pin5 (pin26). Resistor R1, R2 and capacitor C2, external components, for the input
circuit are commended as figure 6. These are requested to use value of the block diagram figure for
performance maintenance of S/N, T.H.D. etc.
Figure 5 shows the relation with R1 front REC IN point and RPOUT.
ALC operation level is 775mVrms {standard level (580mVrms) +2.5dB}. And it is designed to operate
from 0dB to +15dB as 775mVrms=0dB.
Adopted maximum value circuit, ALC is operated by a large channel of a signal.
ALC on/off is linked with REC mute. When REC mute is on, ALC is off.

REC-Equalizer
REC mute is located at input-part of REC-equalizer. Therefore it has realized low pop noise.
But because there is deference DC offset at the each mode of REC-equalizer, it is necessary for a coupling
capacitor between EQOUT pin and recording head.
