Analog to Digital Converter
What is an Analog to Digital Converter?
An Analog to Digital Converter (ADC) is an electronic circuit that converts continuous analog signals into discrete digital values that can be processed by microcontrollers and digital systems. It samples the analog input voltage at regular intervals and represents each sample as a binary number with a specific resolution (such as 8-bit, 10-bit, or 12-bit). ADCs are essential components in embedded systems for reading sensors, processing audio signals, and interfacing real-world analog data with digital processors.

Digital to Analog Converter
DACA Digital to Analog Converter (DAC) is an electronic circuit that converts digital signals (binary data) into analog signals (continuous voltage or current). It takes discrete digital values and produces a corresponding smooth, continuous output signal that can drive speakers, motors, or other analog devices. DACs are essential components in audio systems, display controllers, and any application where digital data needs to interface with the analog world.
Analog Input
An analog input is a pin or channel on a microcontroller, development board, or data acquisition system that can read continuously variable voltage signals. It uses an analog-to-digital converter (ADC) to convert the incoming analog voltage into a digital value that can be processed by the microcontroller. Analog inputs are commonly used to read sensors like temperature sensors, potentiometers, light sensors, and other devices that output varying voltage levels rather than simple on/off digital signals.
