The a/D conversion unit, the a/D converter, can be classified into two types of direct a/D converter and indirect a/D converter according to the principle of conversion. Direct a/D converters, which convert analog signals directly into digital signals, are known as successive approximation converters. The indirect a/D converter converts analog quantity into intermediate quantity, and then converts the intermediate quantity into digital quantity, such as voltage/time conversion type, voltage/frequency conversion type, voltage/pulse width conversion type, etc. The integrating A/D converter has simple circuit, high anti-interference capacity, high resolution and low conversion speed. Some converters integrate a multi-way switch, a reference voltage source, a clock circuit, a decoder and a conversion circuit in one chip, which far exceeds the simple A/D conversion function and is very convenient to use.

A certain time is required to digitize the narrow pulse signal for each sample. Therefore, between two samples, the sampled analog signal should be temporarily stored until the next sampling pulse, which is called hold. In analog circuit design, a sample-and-hold circuit needs to be added. To ensure correct conversion, the analog circuit retains data that has not been converted.
