Data acquisition plays an essential role in extracting expected data from sensors, then the data is converted into digital values via ADC (analog to digital converter). Among various ADC chips, AD7192BRUZ-REEL is one of the most popular. This article aims to introduce its application field and working principles.

AD7192BRUZ-REEL is an 8-channel, 24-bit, high precision, low power ADC with Delta-Sigma modulator and digital filter. It provides simultaneous 8-channel or 4-channel dual-channel inputs with sample rates up to 1600 SPS, and is capable of giving higher precision output data at lower sample rate. With its low power consumption, good EMI and SPI performance, AD7192BRUZ-REEL is more suitable in some applications such as medical, industrial, and instrumentation.

AD7192BRUZ-REEL is an ideal device for numerous applications that require high accuracy and wide dynamic range. For example, it can recognize analog signals in different industrial control systems for measurement of pressure, flow rate and temperature. It is also widely used in medical instruments such as ultrasound imaging, electrocardiography and electroencephalography. In laboratory instrument, it is a perfect match for voltage and current calibration as well as precision balance instrument and test instrument.

To read the converted digital data from AD7192BRUZ-REEL, the SPI interface is used. The SPI interface makes it possible for the AD7192BRUZ-REEL to read 8 parallel channels simultaneously, or 4 differential channels in dual-channel mode. As for power supply, it operates on single +3V to +18V supply voltage range, with 3V and 5V digital supply voltages.

In terms of working principle, AD7192BRUZ-REEL converts analog signals into a digital form using Delta-Sigma Modulator. This modulator consists of a series of 1-bit analog-to-digital converters, which samples and quantizes the input signal. The digital data is sent to digital-filter, where the actual conversion to 24-bit is completed. These digital values are then outputted via the SPI interface.

In conclusion, AD7192BRUZ-REEL is an 8-channel, 24-bit, low power ADC with Delta-Sigma modulator and digital filter. It is widely used in medical instruments, industrial control systems, laboratory instruments, and so on. Through the SPI interface, the AD7192BRUZ-REEL can read 8 channels simultaneously or 4 channels in dual-channel mode. All the conversion process is done with its Delta-Sigma Modulator and digital filter.
