Additionally, it can be used in communication systems such as cellular base stations and satellite receivers.

Working Principle

The ADS7863IDBQG4 utilizes pulse density modulation (PDM) technology to convert an analog signal to a digital output. The system uses an analog switch and a resistor-capacitor (RC) network to generate a pulse stream that is then sampled and decoded by a digital to analog converter (DAC). The RC network is used to set the overall pulse density rate, and the analog switch periodically opens and closes to open and close the RC network. When the RC network is open, the pulse duration is known and can be used to determine the analog voltage level of the input. The DAC then decodes the pulse stream and the digital output is obtained.

The ADS7863IDBQG4 is a low-power and highly integrated data acquisition system, which makes it suitable for a variety of applications. Its high resolution and low noise, low distortion characteristics make it suitable for a wide range of applications, from medical to automotive and communications. The system’s low power consumption and its ability to work with a wide range of interfaces also make it a great choice for designers seeking performance, flexibility, and convenience.
