18-bit, 2-Msps Isolated Data Acquisition Reference Design to Achieve Maximum SNR and Sampling Rate

Overview

TopologyOther Topology

Description

This “18-bit, 2-Msps Isolated Data Acquisition Reference Design to achieve maximum SNR and sampling rate” illustrates how to overcome performance-limiting challenges typical of isolated data acquisition system design:Maximizing sampling rate by minimizing propagation delay introduced by digital isolatorMaximizing high-frequency AC signal chain performance (SNR) by effectively mitigating ADC sampling clock jitter introduced by the digital isolator

Features

18-Bit, 2Msps, 1-Ch, differential input, isolated data acquisition (DAQ) systemLeverages multiSPI™ digital interface of ADS9110 to achieve 2MSPS sampling rate while maintaining a low SPI data rateSource synchronous SPI data transfer mode to minimize isolator propagation delay and improve sampling rateTechniques to reduce Isolator-induced jitter resulting in 12dB improvement in SNR (100kHz Fin, 2-MSPS)Tested design includes theory and calculations, component selection, PCB design, and measurement results

Typical applications

  • Modular DAQ Systems
  • Remote Process Monitoring and Control
  • Design Validation and Verification
  • Data Logging
