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