Dolby B- and C-Type Noise Reduction System
ADE-207-036B (Z)
3rd Edition
Jun. 1999
Description
HA12141/142NT, HA12170NT, HA12161/162FP are silicon monolithic bipolar IC series providing dual
channel Dolby B- and C-type noise reduction* in one chip.
Functions
Dual Dolby B/C-type NR processor
NR OFF/B/C control switch
MPX by-pass / Encode / Decode (MPX OFF / REC / PB) control switch
MPX Filter Drive Circuit
Features
Low external parts count
R-C spectrum skewing network using passive component
External capacitors are E-3 series (small values)
Several time constant capacitors built into the IC
Separate REC/PB input and output. Unprocessed signal output available in the encode and decode
modes.
Common PCB pattern is available with HA12134A series (Dolby B NR), because these ICs offer
similar pin layout.
3 type PB-out level (300 mV, 580 mV, 775 mV)
2 type package (DP-30S, FP-28D)
Wide range of operating supply voltage (7.5 V to 16 V)
