Principle and Working:

ACD (Analog-to-Digital Converter):
An ACD circuit is used to convert analog signals into digital signals. It is commonly employed in various applications, including instrumentation, audio processing, and communication systems.
While analog signals can be continuous and provide an infinite number of different voltage values, digital circuits on the other hand work with binary signals which have only two discrete states, a logic “1” (HIGH) or a logic “0” (LOW). Basically, The ADC takes a continuous analog signal and captures its value at regular intervals.
Digital Value = (Analog Voltage / Reference Voltage) * (2^N - 1)
Analog Voltage is the input voltage you want to convert.
Reference Voltage is the voltage against which the input is measured.
N represents the number of bits or resolution of the ADC.
... DAC(Digital to analogue converter):
Digital to analog converter is an electronic circuit that converts any digital signal (such as a binary signal) into an analog signal (voltage or current).
The DAC receives a digital input, typically in the form of binary numbers. Each bit represents a specific value. For example, an 8-bit DAC has 8 binary bits that can represent 256 different values.
The DAC converts the digital input into an equivalent analog voltage or current. It uses a network of resistors or other components to generate the analog output. Each binary bit contributes to the output voltage or current based on its weight or significance.
The general formula for a basic DAC using uniform quantization:
Analog Voltage = (Digital Value / (2^N - 1)) * Reference Voltage
Digital Value is the input digital value you want to convert.
N represents the number of bits or resolutions of the DAC.
Reference Voltage is the maximum voltage range that the DAC can produce.
