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.
