What Is SAR ADC?
In the modern electronics industry, the Successive Approximation Register (SAR) ADC stands out as an efficient analog-to-digital converter, widely used in applications requiring high precision and rapid response. This article delves into the definition, working principle, characteristics and advantages, and applications of SAR ADCs.
I. What is SAR ADC?
A Successive Approximation Register (SAR) ADC is a type of analog-to-digital converter (ADC) used to convert continuous analog signals into discrete digital signals. Its core feature is the step-by-step approximation method used to achieve accurate digital conversion. SAR ADCs are known for their high precision, fast response, and low power consumption, making them highly effective in various applications.
II. Working Principle
The operation of SAR ADCs relies on a combination of a Successive Approximation Register (SAR) and a Digital-to-Analog Converter (DAC). The basic steps are as follows:
