It can complete the measurement of AC/DC voltage. The running process: it enlarges the digital to tallies chip through Amplifier. It holds the sampling digital pass to convenience transforming for the chip through sample and hold Circuit.

运行过程是：将采样的模拟量通过放大电路放大到和模数转换芯片相适应的量，通过采样保持电路将芯片采样的量保持住后送入模数转换器转换成数字量，再由单片机进行控制计算。

The ADC is pipelined, including a single-input/difference-output sample/hold circuit and nine stage subcircuits. The preceding eight stages are 1.5bits/stage, and the last stage consists of two comparators. Every input sample is converted into 18 bits binary signals, and these binary signals are converted into 10 bits binary signals through digital correction circuit.

模数转换电路采用流水线式的结构，包括具有单端输入/差动输出功能的采样保持电路和九级的子电路，前八级子电路使用1.5位/级的结构，最后一级使用两个比较器实现，每个输入值被转换为18位的二进制代码，通过数字纠正技术最终实现10位的输出，按照前端电路的应用要求，这个模数转换器实现1.33MHz的采样速率。
