HA12161FP Datasheet Dolby B- And C-type Noise Reduction

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HA12141NT, HA12142NT, HA12170NT, HA12161FP, HA12162FP Dolby B- and C-Type Noise Reduction System ADE-207-036B (Z) 3rd Edition Jun.

General 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

Key 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.
