HA12161FP Datasheet | Hitachi Semiconductor

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 ponent - 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. - mon PCB pattern is available with HA12134A series (Dolby B NR), because these ICs offer similar pin layout. - 3 type PB-out level (300 m V, 580 m V, 775 m V) - 2 type package (DP-30S, FP-28D) - Wide range of operating supply voltage (7.5 V to 16 V) - Dolby is a trademark of Dolby Laboratories Licensing Corporation. A license from Dolby Laboratories Licensing Corporation is required for the use of this IC.
