Data Acquisition - Analog to Digital Converters (ADC)

The Analog to Digital Converter (ADC) is a type of data acquisition device used to convert analog signals into a digital form that can be processed by a computer or other digital device. The most popular ADC used today is the ADC0809, which is used in a wide variety of applications. The specific ADC0809 module that is used in this article is the AMC1203BDUB. This module has an 8-bit resolution, an extended temperature range, and an input voltage range of 0-2Vdc. The AMC1203BDUB is a family of ultra-low-power, single-ended, 8-bit analog-to-digital and digital-to-analog converters. It is typically used as an interface between low-voltage analog sensors, such as pressure, temperature, and light sensors, and microcontrollers or digital signal processors. They have several features that make them suitable for use in demanding applications, such as medical and industrial products. The ADC has a wide range of features, such as 8-bit resolution, single supply operation, wide input voltage range (0-2Vdc), low power consumption (typical power down current of 140µA at 5V), low offset, low temperature coefficient, small package size, low cost, and extended temperature range. This low power consumption and wide input voltage range make the AMC1203BDUB an ideal choice for battery-powered or automotive applications. The working principle of the ADC0809 is based on the successive approximation technique. It consists of two major components: an input stage and an output stage. The input stage amplifies the analog signal to the level required by the successive approximation register (SAR). The SAR then compares the amplified signal with an internal reference voltage in steps, using a binary search technique, until the output signal is an exact replica of the input signal. The output stage of the ADC0809 is responsible for converting the digital data from the successive approximation register into a usable analog output. It does this by first applying a digital-to-analog converter (DAC) which produces a signal that is proportional to the input signal. This signal is then filtered by an RC low-pass filter to remove any noise and other unwanted frequency components. Finally, the signal is amplified and then output from the ADC. In summary, the AMC1203BDUB is a family of ultra-low-power, single-ended, 8-bit analog-to-digital and digital-to-analog converters used in data acquisition and other applications where low power consumption and accuracy are important. It works on the basis of the successive approximation technique, which compares an Amplified analog signal to an internal reference voltage in steps. The output is then converted to an analog signal, filtered, and amplified before being output from the ADC.
