ISO15DWR – TEXAS INSTRUMENTS

The Texas Instruments ISO15DWR is a single-channel, digital isolator employing capacitive coupling technology. It features a 5kVrms isolation voltage rating, exceeding the requirements of many industrial applications demanding high dielectric strength. The device operates with a common-mode voltage range of ±700V, significantly wider than many competing isolators, allowing for robust operation in high-noise environments. Data transmission is achieved at a maximum data rate of 150kbps, sufficient for most industrial control and sensor applications. The ISO15DWR boasts a typical propagation delay of 100ns, contributing to minimal latency in real-time systems._x000D_
