HA12192F/HA12197F/HA12212F Series
Audio Signal Processor for Car Deck
(Decode only Dolby B-type NR with PB Amp.)
ADE-207-167D (Z)
5th Edition
Jun. 1999
Description
HA12192F/HA12197F/HA12212F series are silicon monolithic bipolar ICs providing Dolby noise
reduction system*, music sensor, PB equalizer system in one chip.
Functions
• PB equalizer × 2 channel
• Music sensor × 1 channel
• Decode only Dolby B-NR
× 2 channel
Note: HA12197F series is not built in Dolby B-NR.
Features
• Different type of PB equalizer characteristics selection (120µ / 70µ position) is available with fully
electronic control switching built-in.
• Changeable to Forward, Reverse-mode for PB head with fully electronic control switching built-in.
• Available to change music sensing level by external resistor.
• Available to change frequency response of music sensor by external capacitor.
• NR ON/OFF fully electronic control switching built-in. (HA12192F/HA12212F series only)
• Available to connect direct with MPU.
• HA12192F series, HA12197F series and HA12212F available to allow common PCB designs.
• HA12212F only changes by package from HA12192F series. It is the same electrical characteristics
that HA12192F series.

Operating Mode Control
HA12192F series and HA12197F series provides fully electronic switching circuits. And each operating
mode control are controlled by parallel data (DC voltage).

Note:
1. Each pins are on pulled down with 100kΩ internal resistor. Therefore, it will be low-level when
each pins are open.
2. Over shoot level and under shoot level of input signal must be the standardized.
(High: 5.3V, Low: –0.2V)
3. Reducing pop noise is so much better for 10kΩ to 22kΩ resistor and 1µF to 22µF capacitor
