HA12167FB/HA12169FB

Audio Signal Processor for Cassette Deck (Deck 1 Chip)

ADE-207-110B (Z)

3rd. Edition

June 1997

Description

HA12167FB/HA12169FB is silicon monolithic bipolar IC providing REC volume system, Level meter

system and Dolby noise reduction system in one chip.

Functions

•

REC equalizer

× 2 channel

Equalizer volume

Dolby B/C NR

REC/PB input electronic volume

Level Meter

DAC for adjusting bias

Features

•

Available to create characteristics of REC equalizer by changing external resistor, no coil

Equalizer volume is available to calibrate recording automatically with micro-controller

Electronic volume built-in is available to set the level of recording and play back automatically with

micro-controller

•

4 types of input (3 out of 4 are by way of electronic volume)

Input electronic control switching is irrelevant to REC/PB electronic control switching

Dolby noise reduction system is available with double cassette decks (Unprocessed signal output

available from recording out terminals during PB mode)

•

Log-compressed level meter output is range from 0 V to 5 V (Usable as music search switchable gain of

0 dB and 20 dB respectively)

•

Normal-speed/high-speed, normal/metal/chrome fully electronic control switching built-in

NR-ON/OFF, Dolby B/C, MPX ON/OFF fully electronic control switching built-in

Reduction of the number of pins by transfered serial data to electronic volume control switching and

another control switching (Controllable from micro-controller directly)

•

Small the number of external parts
