This document provides the information to assist the design engineer in implementing a low-noise, high-resolution, acquisition system with the PGA855-ADS127Lx1 according to the specific application needs.
The delta-sigma ADC provides a trade-off between the output data rate versus the system bandwidth and noise performance. The PGA855-ADS127Lx1 noise calculator provides an estimate of the intrinsic noise and SNR performance of the acquisition system, facilitating the design for data rate and digital filter settings selection per the bandwidth and resolution requirements.
