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

  • Isolated 18-Bit, 2-MSPS, Single-Channel,Differential Input Data Acquisition (DAQ) System
  • Leverages multiSPI™ Digital Interface of ADS9110to Achieve 2-MSPS Sampling Rate WhileMaintaining Low SPI CLK Speed
  • ADC Clock Master Mode and Source-SynchronousSPI Data Transfer Minimizes Digital IsolatorPropagation Delay and Increases Throughput
  • Optimized Jitter Reduction Techniques EmployedResults in 12-dB SNR Improvement (100-kHz fIN,2-MSPS)
  • Includes Theory, Calculations, ComponentSelection, PCB Design, and Measurement Results

Typical applications

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