Product details

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. 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, 7.
