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 Co r por ation is required for the use of this IC.

Functional Description

Power Supply Range

HA12141 series are designed to operate on either single supply or split supply. The operating range of the
supply voltage is shown in table 1.

Table 1 Supply Voltage

Type No. Single supply Split supply

HA12141NT
HA1211161FP

HA12142NT
HA12162FP

HA12170NT 12 to 16 volts ±6 to ±8 volts

The lower limit of supply voltage depends on the line output reference level.

The minimum value of the overload margin is specified as 12 dB by Dolby Laboratories.

HA12141 series are provided with 3 line output level, which will permit an optimum overload margin for
power supply conditions.

7.5 to 16 volts ±3.8 to ±8 volts

9.5 to 16 volts ±4.8 to ±8 volts

Reference Voltage

For the single supply operation these devices generate the reference voltage of half the supply voltage that
is the signal grounds. As the peculiarity of th ese devices the capacitor for the ripple filter is very small
about 1/100 compared with conventional devices.

The reference voltage supplies are provided for the left channel and the right channel. The block-diagram
is shown as figure 1.

Operation Mode Control

HA12141 series provide fully electronic switching circuits. The function are controlled by DC voltage and
are NR OFF/B/C and PB/REC/MPX.

The switching truth tables are shown in table 2 and table 3.

Table 2 Switching Truth Table (NR OFF /B/C)

Function Single supply Split supply Unit Note

NR OFF 0 to VCC/2 – 3 VEE to –3 V
B type VCC/2 – 0.5 to VCC/2 + 0.5 –0.5 to 0.5 V *1
C type VCC/2 + 3 to V

Note: 1. These functions are available for being open at NR B mode and REC mode

MPX-off mode means that signal from inpu t amp d oesn’t go through the MPX filter, but signal goes
through the SS circuit after being attenuated 3 dB by internal resistor. Refer to figure 2.

Figure 2 The Block-Diagram of MPX Driving Circuit

It is to be desired that CR time constant circuits are provided at NR OFF/B/C terminal and PB/REC/MPX
terminal with time constant from 0.1 sec to 1 sec. If so, it will reduce the switching click noise effectively.

Application Circuits

1. HA12161FP/62FP application
HA12161FP/62FP are developed for exclusive playback of car stereo players.
But these devices are provided with AUX input. This application providing AUX input is available for

car stereo players and car stereo cassette decks.
AUX input will be useful for a tuner input. In this case PB/REC/MPX switching operates as the

switching of PB/AUX1/AUX2.
