HA12226F/HA12227F Audio Signal Processor for Cassette Deck (Dolby B-type NR with Recording System) ADE-207-270E (Z) 6th Edition Dec. 2000 Description The HA12226F/HA12227F are silicon monolithic bipolar IC providing Dolby noise reduction system* , music sensor system, REC equalizer system and each electronic control switch in one chip. Note: 1. Dolby is a trademark of Dolby Laboratories Licensing Corporation. A license from Dolby Laboratories Licensing Corporation is required for the use of this IC. The HA12227F is not built-in Dolby B-NR. 1 Functions • Dolby B-NR* • Music sensor • Pass amp. 2 × 2 channel × 2 channel × 1 channel × 2 channel • REC equalizer • Each electronic control switch to change REC equalizer, bias, etc. Note: 2. The HA12227F is not built-in Dolby B-NR. 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. 2 • 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, Normal / Crom and PB equalizer fully electronic control switching built-in. • Available to reduce substrate-area because of high integration and small external parts. HA12226F/HA12227F Ordering Information Operating Voltage Product HA12226F HA12227F Power Supply Range (Single Supply) 11.0 V to 15.0 V 9.5 V to 15.0 V Standard Level Product HA12226F HA12227F Package FP-56A PB-OUT Level 580 mVrms REC-OUT Level 300 mVrms Dolby Level 300 mVrms  Function Music Sensor ❍ ❍ REC / PB Selection ❍ ❍ Product HA12226F HA12227F Dolby B-NR ❍ × REC-EQ ❍ ❍ Pass Amp. ❍ ❍ ALC ❍ ❍ Note: Depending on the employed REC / PB head and test tape characteristics, there is a rare case that the REC-EQ characteristics of this LSI can not be matched to the required characteristics because of built-in resistors which determined the REC-EQ parameters in this case, please inquire the responsible agent because the adjustment built-in resistor is necessary. Difference of HA12215F and HA12226F/HA12227F Tape Correspondence Product HA12226F/HA12227F HA12215F Supply Voltage Single supply voltage Split supply voltage NORM ❍ ❍ CROM ❍ ❍ METAL × ❍ Note: The HA12226F/HA12227F became single power supply for the HA12215F and deleted metal correspondence. The HA12227F is not built-in Dolby B-NR. Other characteristic aspects are similar as the HA12215F. Rev.6, Dec. 2000, page 2 of 86 HA12226F/HA12227F Pin Description, Equivalent Circuit (VCC = 12 V, A system of single supply voltage, Ta = 25°C, No Signal, The value in the show typical value.) Pin No. 51 Terminal Name AIN (R) Note V = VC.
