Description
HA12209F is silicon monolithic bipolar IC providing Dolby noise reduction system*, music sensor system,
REC equalizer system and each electronic control switch in one chip.
Functions
• Dolby B-NR
× 2 channel
• REC equalizer
× 2 channel
• Music sensor
× 1 channel
• Each electronic control switch to change REC equalizer, bias, etc.
Features
• REC equalizer is very small number of external parts and have 4 types of frequency characteristics
built-in.
• 2 types of input for PB, 1 type of input for REC.
• 70µ-PB equalizer changing system built-in.
• Dolby NR with dubbing double cassette decks.
Unprocessed signal output available from recording out terminals during PB mode.
• Provide stable music sensor system, available to design music sensing time and level.
• Controllable from direct micro-computer output.
• Bias oscillator control switch built-in.
• NR ON/OFF and REC/PB fully electronic control switching built-in.
• Normal-speed/high-speed, TYPE I/TYPE II and PB equalizer fully electronic control switching built-in.
• Available to reduce substrate-area because of high integration and small external parts.
