ZYNQ-Based Real-Time Data Logger
A high-speed, multi-channel data acquisition system designed using the ZYNQ XC7Z020 SoC and the 24-bit AD7768 ADC.
This system features a sampling rate of 256 kSPS and real-time data transfer over Ethernet, making it ideal for industrial measurement, power monitoring, and medical applications. It captures and processes analog signals using ADA4807 precision amplifiers and a delta-sigma ADC. The architecture efficiently bridges programmable logic and ARM processors for concurrent data processing and transmission.
