Working Principle

The ADS7851IRTET is based on the dual-slope integrating technique. This method works by charging and discharging a capacitor using two different reference voltages. At the beginning of the process, a reference voltage is applied to the capacitor, which charges it up. Afterward, a second, opposite voltage is applied and the capacitor starts discharging. Once it stops, the voltage across it is compared to the reference voltage, and a digital value is obtained.

The main advantage of the dual-slope integrating technique is that it yields a steady output over a wide range of frequencies. This allows for sensitive signals to be measured precisely, even if they contain noise or other interfering signals.

The ADS7851IRTET employs this technique in a unique way. Instead of having a single reference voltage, it uses two, allowing it to monitor both input and output voltages. This improves the accuracy of the conversion process, enabling the ADC to provide accurate results even in noisy environments.

Conclusion

The ADS7851IRTET is a reliable and accurate analog-to-digital converter. It is used in a variety of applications, ranging from medical equipment to automotive instrumentation. The device is based on the dual-slope integrating technique, which allows it to provide accurate results even in noisy environments.
