PCM1753DBQ is a high performance, low-cost, 12-bit resolution, special purpose sigma-delta analog-to-digital converter (ADC). It operates from 8MHz to 20MHz, and has an integrated 16-bit Delta-Sigma modulator. This device is suitable for a variety of industrial and consumer applications.

The PCM1753DBQ is designed for applications such as temperature and pressure sensing, motor control, color sensing, and interfacing with sensors and microcontrollers. It provides accurate and reliable measurements, and can be used for a variety of applications such as audio processing, medical diagnostics, environmental testing and measurement, automotive, and industrial control.

The PCM1753DBQ offers a full range of features to maximize user convenience. It is equipped with an on-chip temperature sensor for temperature compensation, along with multiple gain settings for analog input range selection. It also offers digital output modes such as pulse-width modulation (PWM), and serial peripheral interface (SPI). Additionally, it supports multiple operating modes, including single-channel conversion mode, ramped-up-sampling and sequential multi-channel sampling mode. These features allow the user to customize the operation of the device to their specific application requirements.

The working principle of a sigma-delta ADC is based on oversampling and then noise-shaping, which is accomplished by summing or subtracting the output of the modulator with a delayed version of the input signal. When the input signal is periodically sampled, an analog-to-digital conversion is performed, and the result is a 16-bit digital word that is output on the digital port. The modulator then operates very quickly in order to rapidly convert the input signal into a larger number of more accurate data points, thus providing higher resolution.

In addition to its robust set of features and operation modes, the PCM1753DBQ offers a low power consumption, low noise performance, and low EMI levels. This makes it ideal for a variety of applications, such as medical diagnostics, environmental measurements, automotive and industrial control, and many more. Furthermore, the device is RoHS compliant and offers high immunity to ESD.

The PCM1753DBQ is a powerful and versatile device that is well suited for a variety of applications. It offers accurate and reliable measurements, and is capable of operating at high speeds. It also offers multiple gain settings for analog input range selection, and supports digital output modes such as pulse-width modulation and serial peripheral mode. With its robust feature set and user-friendly interface, the PCM1753DBQ is an ideal solution for any application requiring accurate and reliable measurements.
