摘要：以下讨论验证了一个被现存A/D转换器应用所忽略的选择：有些条件下采用分立的比较器和D/A转换器更容易实现A/D转换。这种替代方案通常采用不同的测试方法，但是具有低成本、高速度、更大灵活性以及更低功耗等优点。利用比较器/DAC组合解决数据采集问题Mar01,2012摘要：以下讨论验证了一个被现存A/D转换器应用所忽略的选择：有些条件下采用分立的比较器和D/A转换器更容易实现A/D转换。这种替代方案通常采用不同的测试方法，但是具有低成本、高速度、更大灵活性以及更低功耗等优点。尽管当前趋势全部集中一个方向―设计者需要使用A/D转换器时通常选定一个集成的A/D转换器(ADC)。大多数工程师并没有意识到还有降低ADC性价比的其它替代方案。而模拟比较器、D/A转换器(DAC)和信号处理一起恰好就是构成逐次逼近ADC的核心电路。某些特定领域，分立比较器/DAC的使用非常普遍。自动测试设备、核脉冲反应堆高度监测器以及自动化时域反射计等，通常都采用这种技术，DAC用于驱动比较器的一个输入，另一个输入由被监测信号驱动。接下来是通用测试问题以及特定方法的选择，事实上，此时采用比较器/DAC组合比采用现成的ADC更受欢迎。瞬态电压分析捕获快速幅度变化事件(瞬态)的“强力”技术就是采用处理器支持的高速ADC和RAM对其进行简单量化(图1)。单触发事件可能必须采用这种方法，因为需要获取瞬态细节。然而，如果瞬态是重复性的，则可采用DAC/比较器的方法测量它们的峰值幅度及其它特性(图2)。图1.采用“强力”法进行瞬态分析，ADC电路耗电大且价格昂贵图2.如果图1应用可接受对幅度进行重复测量，用DAC/比较器组合替代ADC可省电并降低成本比较器的一个输入引脚由DAC设置判定电平，瞬态信号施加到另一个输入。通过调整DAC输出可确定峰值瞬态幅度，超越门限时，采用数字锁存捕获比较器的输出响应。仅需要比较器输入支持瞬态带宽，任意长的DAC输出建立时间并不会影响测量精度。这样，在模拟域可用低成本DAC和……
