日本NEC公司生产的μPC1353C电视伴音通道集成电路,是一种成熟的音频放大集成电路,它应用于国内许多厂家生产的黑白电视机中,作伴音信号的伴音中放、解调、放大和功率输出。μPCI353C集成电路的应用基本相同,均在鉴频中放部分的工作电压脚⑤端与地串接一电位器,从中取出不同的电位加到(14)脚,来实现音量控制功能。从有关资料查得,该集成块
Japan NEC’s μPC1353C TV channel audio integrated circuits, is a mature audio amplifier IC, which is used in many domestic manufacturers of black and white TV sets, as audio signal sound amplifier, demodulation, amplification and power output . μPCI353C IC applications are basically the same, are part of the frequency discrimination in the work of the voltage pin ⑤ end and ground in series with a potentiometer, from which different potentials added to (14) feet, to achieve volume control. From the information found, the block
