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.

The operating range of the supply voltage is shown in table 1. Table 1 Supply Voltage Type No. Single supply Split supply HA12141NT HA1211161FP 7.5 to 16 volts ±3.8 to ±8 volts HA12142NT HA12162FP 9.5 to 16 volts ±4.8 to ±8 volts 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. 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 these 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. 23 VCC + — Lch Reference 4 1 µF Rch Reference + — + 8 Figure 1 The Block-Diagram of Reference Voltage Supply Rev.3, Jun. 1999, page 57 of 63 HA12141NT, HA12142NT, HA12170NT, HA12161FP, HA12162FP 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 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 VCC/2 + 3 to VCC 3 to VCC V C type Note: Note *1 1.

These functions are available for being open at NR B mode and REC mode. 2. MPX-OFF mode control Voltage of HA12170NT is available with range from VCC – 2 to VCC. MPX-off mode means that signal from input amp doesn’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.

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.
