5000 Vrms isolation in a 16-SOIC — what it buys you
The ADUM2211SRIZ is a 2-channel, unidirectional digital isolator from the iCoupler family, using magnetic coupling to pass signals across a 5000 Vrms isolation barrier. It is a General Purpose part, meaning it handles logic-level signals without integrated power conversion — the isolated side needs its own supply rail. Two channels with a 1/1 input-side/side-2 split cover one transmit and one receive path, or two independent forward signals. The 1 Mbps data rate and 150 ns propagation delay (max) suit moderate-speed interfaces like SPI, UART, or GPIO isolation where timing margin is not single-digit nanosecond.
