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 × 2 channel REC equalizer × 2 channel Each electronic control switch to change REC/PB etc. REC MUTE REC head return switch 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.

Table 1 Supply Voltage Item Power Supply Range Single Supply 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. 1 VCC Lch PB-EQ Reference voltage Lch REC-EQ Reference voltage 470Ω Rch REC-EQ Reference voltage Rch PB-EQ Reference voltage 22 7 GND Vref + 470µF Figure 1 Reference Voltage Circuit 7 HA12207NT 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 Control Voltage (Vth) Pin No. Lo Hi Unit 16, 17 0.0 to 1.0 4.0 to VCC V Test Condition Input Pin Measure V 18 Note: 0.0 to 3.0 4.0 to VCC V 1. Each pin is pulled down with 100kΩ 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.

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 5.6kΩ. 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. 300mV (Dolby level) HA12134A 63.6mV 0.6mV 40.5dB 20dB Dolby IC PB-EQ Figure 3 PB Level Block Diagram (Normal Speed, 1kHz) 1.8V REC - EQ Clip level 300mV (Dolby level) 263mV 100mV 1kHz REC - EQ Figure 4 REC Level Block Diagram (Normal Speed, 1kHz) 9 HA12207NT Absolute Maximum Rating (Ta = 25°C) Item Symbol Rating Unit Max supply voltage VCC max 16 V Power dissipation Pd 500 mW Operating temperature Topr –40 to +75 °C Storage temperature Tstg –55 to +125 °C Operating voltage Vopr 9.5 to 15 V Note: HA12207NT operates on single supply voltage. 10 Note Ta≤75°C 60 CT A/B PB-EQ crosstalk Note: 1.
