Data Acquisition Analog to Digital Converters (ADC) are devices which are used to convert analog signals into digital representation. An Analog to Digital Converter, more commonly known as an ADC, is a device that takes an in – analog voltage values, such as a thermocouple input or an analog transducer signal – and convert it into a digital representation of that sound wave. This digital representation can then be used for computing purposes, such as in instrumentation and data logging, control systems, and embedded systems. It takes the analog input signal, samples the signal at regular intervals, and uses a digital representation of the signal for further processing.

In this article, we will be discussing the application field and working principle of the AD7475BR, an analog to digital converter (ADC) from Analog Devices, Inc. This 8-bit, serial-output analog to digital converter is designed with a single 5V power supply and has a wide operating range, making it ideal for space-constrained applications. The converter is designed to offer accurate conversion with high resolution and low power consumption, making it an ideal choice for various applications.

The AD7475BR ADC is used in a wide range of applications such as medical, industrial, and consumer electronics. Some of the common applications include measuring temperature, light, pressure, and force. The ADC has a maximum sampling rate of 200 ksps and is capable of handling input signal ranges from 0V to 5V. The AD7475BR is capable of processing digital signal streams at low power consumption. It provides efficient sampling, low noise, and low power consumption, making it an ideal choice for portable and battery-operated applications.

The working principle of the AD7475BR is based on the technique of sample and hold. In this technique, an analog signal is applied to the input of the ADC which is sampled at regular intervals, and then converted into digital information for further processing. The conversion is performed by a single analog-to-digital converter, which samples the analog signal, converts it into its digital representation, and stores the digital information in a register at the output of the ADC.

The AD7475BR features a three-state output register and a triggerable parallel output. It also features an internal clock that synchronizes the sampling and conversion process. The clock also allows for low power consumption and a low noise floor. The converter incorporates two 8-bit channels, enabling simultaneous sampling of two different input signals. It has an integrated gain control that adjusts the gain up to 4 times. It also provides a 5-point calibration to reduce the total differential nonlinearity of the conversion.

The AD7475BR is designed to be used in a variety of applications. With its wide operating temperature range, it is ideal for harsh environment applications. It is also suitable for medical, industrial, and consumer applications as it has high resolution, accurate conversion, and power efficiency. This makes the AD7475BR an ideal choice for a wide range of data acquisition applications.
