HA12142NT 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)
