25 Mbps unidirectional quad isolator — what it fits and what it doesn't
The ADUM3480BRSZ is a four-channel, unidirectional digital isolator from Analog Devices' iCoupler series, built around magnetic coupling technology. It delivers 25 Mbps per channel with a propagation delay of 33 ns max and 2.5 ns typical rise/fall times.
Supply range and temperature — industrial and automotive ready
No isolated power converter is integrated, so you still need a separate DC-DC for the secondary-side rail.
Package and footprint — 20-SSOP
Housed in a 20-SSOP package (5.30 mm body width, 0.209" pitch), surface-mount only. The 20-SSOP footprint is common across the ADUM3480 family, so swapping density options keeps the same board layout.
The product status is Active and ROHS3 Compliant. The iCoupler series has broad second-source coverage from competitors, but no pin-compatible alternate is cited in the ledger.
