在现代电子学的应用领域中,模数转换(ADC)和数模转换(DAC)技术的地位越来越重要,它是仪器仪表数字化、智能化、自动化不可缺少的手段。随着微处理机的广泛应用,工业自动化程度提高,对 ADC 和 DAC 器件的需求量与日俱增。众所周知,要实现程控电流源、电压源、信号源,程控转速、压力、温度,程控滤波器、解码器、调制器等等,DAC 数模转换器是不可缺少的组成部分。上海元件五厂计划研制的5G7621十二位二进制单
In the field of application of modern electronics, the status of analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC) technology is becoming more and more important. It is an indispensable means of digitizing, intelligentizing and automating instrumentation. With the widespread use of microprocessors, industrial automation increases the demand for ADCs and DAC devices. As we all know, to achieve programmable current source, voltage source, signal source, programmed speed, pressure, temperature, programmable filters, decoders, modulators, DAC digital to analog converter is an integral part.
