TIDA-01037 最大程度提升 SNR 和采样速率的 20 位、1MSPS 隔离器优化型数据采集参考设计
TIDA-01037 是一款 20 位、1MSPS 隔离式模拟输入数据采集参考设计，使用两种不同隔离器器件，以最大限度地提高信号链 SNR 和采样率性能。对于需要低抖动的信号（例如 ADC 采样时钟），可使用 TI 的 ISO73xx 系列低抖动器件；而 TI 的高速 ISO78xx 系列器件则用于最大限度地提高数据采样率。通过结合这两种隔离器解决方案，可跨隔离边界最大限度地降低采样时钟抖动，使高频性能得到显著提高，并且可利用最大限度提高隔离器信号传输速率的方式提高数据吞吐量。通过使用 TI 的高级 ADC multiSPITM 和源同步功能，还可实现进一步改善。最后，说明了所有重要设计理论并展示了测量结果。

Class 4- Flyback 50V@0.5A for PoE Applications
PMP5435 is an offline power supply that provides 50 watts of output power to two outputs. The outputs are 5 volts at 5 amps and 50 volts at 0.5 amps. A flyback topology is used to provide isolation from the high voltage in to a 12 and 48 volt output. The 5 volts is provided by a buck regulator powered from the 12 volts. These is also a serial data power provided that allows the monitoring of current: voltage ant temperature information.
