HA12134A, HA12135A, HA12136A
Dolby B-Type Noise Reduction System
ADE-207-016B (Z)
3rd Edition
Jun. 1999
Description
The HA12134A, HA12135A, HA12136A are silicon monolithic bipolar IC series providing dual channel
Dolby B-type noise reduction system* in one chip. The circuit is used primarily to reduce the level of
background noise introduced during recording and playback of audio signals on magnetic tape.
HA12134A series provide the following functions and features.
Functions
Dual Dolby B-type NR processor
NR ON/OFF control switch.
Record (encode)/playback (decode) control switch.
Features
Separate record/playback input and output.
Unprocessed signal output available in the encode and decode modes.
Reduction of external components count.
Small capacitor value for the reference voltage.
NR ON/OFF switching and REC/PB switching are provided internally.
2-type package (DP-16, FP-16DA)
Wide range of operating supply voltage.
