The ADUM160N0BRZ is a 6-channel unidirectional digital isolator from Analog Devices using iCoupler magnetic coupling technology. It packs six independent isolation channels in a 16-SOIC narrow-body package, all rated for 3000 Vrms isolation with a 75 kV/µs common-mode transient immunity floor. The 150 Mbps data rate per channel is fast enough for SPI clock lines up to 75 MHz (double-edge) or multiple parallel GPIO signals without bottlenecking the bus.
Timing margins that matter for high-speed isolation
Propagation delay is 13 ns max in either direction, with pulse-width distortion held to 4.5 ns max. Rise and fall times are a symmetrical 2.5 ns typical. For a 150 Mbps NRZ signal (6.67 ns bit period), that 13 ns prop delay eats roughly two bit periods end-to-end — fine for most SPI frames where the master adds wait states, but budget it in the timing closure if you are running back-to-back transactions at full rate.
All six inputs on one side — layout note
The channel assignment is 6 inputs on Side 1, 0 on Side 2 — meaning all six channels run in the same direction. That makes this part a straight-through isolator for six parallel signals from a microcontroller to a peripheral (e.g., SPI + three GPIOs). If you need bidirectional channels or mixed input/output assignments, look at the ADuM160N family variants with different Side 1/Side 2 splits.
Package and compliance
Housed in a 16-SOIC narrow-body (3.90 mm width) — the same footprint used across the ADuM160N series, so a layout done for one variant accepts the others. Surface-mount only. ROHS3 compliant per the listing.
