What is the conversion time of an ADC?

The device that makes conversions of analog signals to a digital form is the analog-to-digital converter (ADC). Every ADC requires a certain amount of time to perform the A/D conversion. A typical ADC device is characterized by a maximum conversion time of 40 μs.

What is the minimum conversion time for ADC?

Table 14.8 tells us that the ADC clock frequency should have a maximum value of 13 MHz, and that it takes 65 cycles of the ADC clock to complete a conversion. A quick calculation shows that the minimum conversion time possible is therefore 5 μs.

Which ADC has fastest conversion rate?

Flash ADC (Fastest)

The flash ADC is the fastest type available. A flash ADC uses comparators, one per voltage step, and a string of resistors.

What is delta-sigma conversion?

Delta-sigma modulation converts an analog voltage signal into a pulse frequency, or pulse density, which can be understood as pulse-density modulation (PDM).
