The ADC can either be integrated within the MCU chip itself or a standalone IC that you can interface with Serial/Parallel ports of your microcontroller. The type of ADC depends on how it’s performing the quantization process, it can be analog integration, digital counter, successive approximation, or even direct conversion as in Flash ADC types which we’ll discuss hereafter.įinally, the digital output data is served to the CPU or gets directly stored in memory.
Followed by a quantized which is actually the working horse for the analog to the digital conversion process. The basic structure of an ADC consists of an S/H circuit (Sample & Hold). Why do we need to use ADC in the first place? And depending on how it works and how well it gets the job done, you pay more or less respectively per ADC unit.Īnd before any further investigation for ADC types and technical details of working principles, let us question about the usefulness of A/D conversion. There are many different types of A/D converters out there.
The electronic device which is used for this conversion process has been known to be the A/D or ADC (Analog-To-Digital Converter).
#8 BIT ANALOG TO DIGITAL CONVERTER SERIES#
It’s a process of capturing the analog electric signal (such as sound captured by a microphone) and converting it to a series of numeric “Digital” values to be stored/processed by a digital computer or DSP.
