Data Acquisition usually involves measuring analog signals from a environment of interest and converting them into digital signals for analysis. Analog-to-Digital Converters (ADCs) are the building blocks of most data acquisition systems as they provide the interface between the analog and digital worlds for data-acquisition processing. The AD7475BRMZ-REEL7 is one such ADC offering professional data-acquisition applications.

The AD7475BRMZ-REEL7 is a low power, 16-bit, single-channel sampling ADC that has a programmable differential input range of 6 Vp-p. It is capable of sampling up to 200 kHz with 70 dB SNR and an 83 dB total harmonic distortion. It also includes a unique current reference feature that allows it to achieve a very low power consumption of only 6 mA. It also has on chip internal temperature sensing for precise temperature measurement. This makes the device ideal for instrumentation and medical applications.

The AD7475BRMZ-REEL7 device has several features that make it useful for a variety of applications. It has an on-chip voltage reference, an internal synchronized clock, and an on-chip I2C compatible serial interface. The chip is capable of multiple input ranges and has both sample-and-hold and differential inputs. The power consumption of the device is extremely low, making it ideal for remote data acquisition applications.

The AD7475BRMZ-REEL7 device integrates a low power, low-noise 10-bit, 200 kHz sampling ADC and an on-chip precision voltage reference. It also includes a programmable offset and gain error correction. The wide differential input range makes it suitable for remote sensing applications, instrumentation and medical applications. The AD7475BRMZ-REEL7 has 6 Vpp input range and a programmable gain of up to 128 dB, resulting in an SNR of 70 dB and a THD of 83 dB.

The working principle of the AD7475BRMZ-REEL7 is based on the charge-redistribution successive approximation register (SAR) architecture. The SAR is composed of n capacitors and n-1 switches, where n is the resolution of the ADC. The input to the SAR is compared to internal reference. This comparison process is done for each stage of SAR, until the output voltage is equal to the reference voltage. This process makes it possible to convert the analog input signal into the digital bit-stream.

In summary, the AD7475BRMZ-REEL7 is a high performance, low-power analog to digital converter ideal for data-acquisition applications. It has a wide input range with programmable gain and low-noise analog circuit design. It also has an on-chip temperature sensor, synchronized clock, and I2C serial interface. It is capable of sampling up to 200 kHz with very good SNR and total harmonic distortion. The AD7475BRMZ-REEL7 using the charge-redistribution successive approximation register architecture which allows the ADC to convert the analog input signal into the digital bit-stream.
