![]() The Digital output from the Comparators acts as input to Encoder. Reference Voltage (Vref) is supplied to the Comparator through external source. It is also known as Parallel ADC.įig.3 below illustrates block diagram of Analog to Digital Converter (ADC) where Analog input is connected to all comparators so that the output is generated simultaneously. Hence, Flash ADCs are used in the applications which requires High-speed and large bandwidth. The operation of Flash ADC is the fastest compared to all other ADCs. The different types of Analog to Digital Converters (ADCs) are: 2 – Schematic Diagram of ADC Types of Analog to Digital Converter It can also be defined as a device that provides a digital output which is the representation of the input voltage or current level.įig. 1 – Introduction to Analog to Digital Converter Examples of physical variables include audio signals, temperature, pressure etc.įig. They have high conversion efficiency and requires less power. ![]() What is Analog to Digital Converter (ADC)Īnalog to Digital Converter (ADC) basically converts physical variables which are analog in nature to digital signal for processing. This post will discuss about what is an Analog to Digital Converter (ADC), its various types, how it works, applications, advantages and disadvantages. ![]() ![]() Analog to Digital Converter (ADC) is an integrated circuit which helps to transform analog signal to digital form.
