Six channels at 150 Mbps with 5 kV isolation — the BOM-fit tier for industrial signal isolation
The ADUM262N1BRIZ-RL is a 6-channel, unidirectional digital isolator from Analog Devices' iCoupler series, built around magnetic coupling technology. It delivers 150 Mbps per channel with a propagation delay of 13 ns max and pulse-width distortion under 4.5 ns, making it fast enough for SPI, UART, and CAN buses without adding timing headaches.
Supply range and channel layout — what fits the board
The 4/2 input split — four channels on side 1, two on side 2 — maps naturally to a 4-wire SPI bus (SCLK, MOSI, MISO, CS) plus two control signals on the return side.
The 5000 Vrms isolation is tested per UL 1577 and VDE 0884-10; the 75 kV/µs CMTI means it won't glitch when an IGBT switches 600 V in a few nanoseconds.
The iCoupler series has broad second-source coverage from ADI's own pin-compatible variants, but no direct cross-reference is listed in the ledger.
