Working Principle
The DSD1791DBRG4 is a sigma-delta ADC that uses an oversampling technique to achieve high precision and low noise levels. The ADC takes an analog input signal, filters it, and digitizes it with a series of comparators. The comparator output is used to generate a digital output that is then averaged over several cycles of the ADC operation. This averaging process is called oversampling, and it reduces the effects of noise on the resulting digital output.
The DSD1791DBRG4 also incorporates programmable input ranges, enabling it to accept input signals from different sensor and transducer types. It can be used with resistive sensors, capacitive sensors, and most types of transducers. Additionally, the ADC can be programmed to adjust its gain and resolution according to the input signal, providing flexible and accurate digital outputs.
Finally, the DSD1791DBRG4 features a high-speed interface, allowing for fast data exchange between the ADC and the system processor. The interface is compatible with various bus protocols, making it compatible with a variety of host processors and peripherals. The ADC alsohas power management capabilities, enabling it to reduce power consumption when it is not in use.
