Three-channel iCoupler with 150 Mbps throughput
The ADUM131D0BRZ-RL7 is a 3-channel digital isolator from ADI's iCoupler family, built around magnetic coupling technology. It delivers 150 Mbps data rate across a 3000 Vrms isolation barrier, with a propagation delay of 13 ns max and 2.5 ns rise/fall times. The unidirectional channel configuration provides two inputs on side 1 and one input on side 2, making it a straightforward fit for isolating SPI, UART, or general-purpose digital signals where the data flow direction is fixed.
75 kV/µs CMTI — noise immunity for motor drives and inverters
Common-mode transient immunity is rated at 75 kV/µs minimum, which is the figure that matters when the isolator sits between a noisy power stage and a sensitive controller. In a variable-frequency motor drive or a switched-mode power supply, fast voltage transients on the isolation barrier can couple through parasitic capacitance and corrupt data. The 75 kV/µs rating means this part maintains data integrity through those events without bit errors.
Industrial temperature range and wide supply compatibility
This simplifies the BOM when bridging low-voltage MCU domains to higher-voltage peripheral rails.
Active lifecycle — no end-of-life concern for new designs
ADI lists the ADUM131D0BRZ-RL7 as Active in production.
