A SAR ADC converter, or successive approximation register analog-to-digital converter, converts an analog input voltage into a digital code by testing one bit at a time. Rather than measuring every

The difference between an ADC and a DAC is the conversion direction. An ADC converts an analog signal into digital data. A DAC converts digital data into an analog signal.

An analog-to-digital converter, usually called an ADC or A/D converter, is the circuit that turns a real-world analog signal into digital numbers a microcontroller, processor, or computer can use. The
