Dolby B- and C-Type Noise Reduction

HA12141NT, HA12142NT, HA12170NT, HA12161FP, HA12162FP 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) * Dolby is a trademark of Dolby Laboratories Licensing Corporation. A license from Dolby Laboratories Licensing Corporation is required for the use of this IC.
