The AD7475BRMZ-REEL is a Data Acquisition – Analog to Digital Converters (ADC) device from Analog Devices, Inc. (ADI). It is a 16-bit, low-power, serial I/O sigma-delta ADC with an integrated digital filter and an 8-channel multiplexer. The device provides high-resolution, low-noise conversion with a wide dynamic range. It has a speed of up to 30 ksps and a maximum sampling rate of 80 kHz. The device also offers an integrated low-pass filter with a full-power bandwidth of 4 kHz.

The AD7475BRMZ-REEL features differential and single-ended input capability, providing a large common-mode input range for the highest performance in either single-ended or differential input configurations. The input accepts either a single-ended or differential voltage and includes a software-programmable gain for each of the 8 input channels. The integrated filter is calibrated for optimal noise performance and includes a gain setting that is tuned for best performance.

The AD7475BRMZ-REEL features an on-chip temperature-compensated reference and a 5-bit DAC reference trim feature to provide high-accuracy operation at the lowest possible power. In addition, it has an on-chip programmable power-down function to reduce the current consumption in idle or sleep modes. The device is available in a 28-pin, 5 mm x 5 mm QFN package.

The AD7475BRMZ-REEL is ideally suited for industrial and automation applications such as weighing systems, motor control, level sensing and control, factory automation, and data acquisition. It is also well-suited for medical systems and laboratory instruments. The device’s low-power consumption makes it suitable for portable and battery-powered applications.

The AD7475BRMZ-REEL works by taking an analog input voltage and converting it into a digital representation. The analog input is sampled and converted according to a predefined sampling rate. The sampling rate determines the resolution of the converted digital data. The device uses an on-chip reference voltage and a series of control signals to set the gain and adjust the likelihood of each input voltage being sampled. The gains are adjusted to ensure that the digital data is accurate and noise-free. The digital data is then passed through a low-pass filter to remove noise and then the output is processed according to the selected data rate.

The AD7475BRMZ-REEL is a highly integrated, low-power, low-noise ADC with a wide dynamic range and high resolution. It is ideal for industrial and automation applications that require high accuracy and low power consumption. The integrated digital filter and 8-channel multiplexer provide enhanced accuracy and flexibility for the user. The device is available in a compact, QFN package and is suitable for portable and battery-powered applications.
