Pin2 is the input pin – High to low pulse brings the data from the internal register to the output pins after conversion. A suitable RC circuit is connected between the clock IN and clock R pins to use the internal clock. An external clock can be given to CLK IN pin no.4. The time taken to convert the analog to digital value depends on the clock source.

It can take only one analog signal as input. It is an 8-bit converter with a 5V power supply. The objective of an A/D converter is to determine the output signal word corresponding to an analog signal. These converters find more applications as an intermediate device to convert the signals from analog to digital form, display output on LCD through a microcontroller. There are many methods to convert analog signals to digital signals. The time taken for the entire conversion can be done within a microsecond. So this is the entire method to change an analog signal to digital using an ADC.

So it is required to change the signal from digital to binary with the help of an encoder. We know that a digital device works by using binary signals. The final block in ADC is an encoder that converts the signal from digital form to binary. Classification of ADCs based on factors like performance, bit rates, power, cost, etc. Dynamic characteristics of the high-performance ADCs are improved measurement repeatability, low power consumption, precise throughput, high linearity, excellent Signal-to-Noise Ratio (SNR), and so on.Ī variety of applications of the ADCs are measurement and control systems, industrial instrumentation, communication systems, and all other sensory-based systems. With the invention of a wide variety of ADC integrated circuits (IC’s), data acquisition from various sensors becomes more accurate and faster. One of the major benefits of ADC converter is the high data acquisition rate even at multiplexed inputs. Bit resolution is nothing but how much accuracy can an analog to digital converter can convert the signal from analog to digital.The sample rate of an ADC is nothing but how fast an ADC can convert the signal from analog to digital.The main features of ADC are sample rate and bit resolution.
