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.

Functional Description

Power Supply Range

Table 1 Supply Voltage

	Power Supply Range
Item	VCC	VEE	| VCC | – | VEE |
Single Supply	6.0V to 7.5V	–7.5V to –6.0V	Inside 1.0V

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).

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

Table 2	Control Voltage
Pin No.	Lo	Mid	Hi	Unit	Test Condition
17, 18, 19	0.0 to 1.0	—	4.0 to V CC	V	Input Pin				Measure

20 0.0 to 1.0 2.0 to 3.0 4.0 to VCC V

Note: 1. Each pin is pulled down with 100kΩ internal resistor. 17 to 19 pins are low-level, 20 pin is midlevel, 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)
