The ADUM7441CRQZ-RL7: It provides galvanic isolation rated at 1000 Vrms between the input and output sides, with a unidirectional channel configuration — three channels on side 1 and one on side 2. Typical applications include isolating SPI, UART, or general-purpose digital I/O lines in industrial automation, motor drives, power supplies, and instrumentation where ground loops or voltage differences between domains must be blocked.
At 25 Mbps, this isolator handles most common serial protocols without timing pressure: SPI up to 25 MHz clock, UART at standard baud rates, and parallel control signals. The 50 ns propagation delay max and 5 ns pulse-width distortion keep the digital eye open across the barrier, so you don't need to derate the bus speed for the isolator. The 1000 Vrms isolation rating is specified for basic insulation. The 15 kV/µs common-mode transient immunity ensures the output does not glitch during fast switching events.
