HA12161FP Overview
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.
HA12161FP Key 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 mV, 580 mV, 775 mV)
- 2 type package (DP-30S, FP-28D)
- Wide range of operating supply voltage (7.5 V to 16 V)
