Product details

Single-channel iCoupler with 100 Mbps throughput

The ADUM3100BRZ-RL7: Typical applications include breaking ground loops in industrial fieldbus interfaces, isolating SPI or UART links in motor drives and PLCs, and providing galvanic isolation in power-supply feedback paths.

Data rate is 100Mbps. Propagation delay max is 18ns, pulse-width distortion max is 2ns, and rise/fall times typ are 3ns each.

25 kV/µs CMTI — survives the switching node

Common-mode transient immunity minimum is 25kV/µs.

The 3V to 5.5V supply range on each side is independent, so you can run the controller side at 3.3V and the isolated side at 5V (or any combination in between). No isolated power converter on-chip (the Isolated Power spec is No), so you need a separate isolated DC-DC or a rail from the bus side to power the secondary.

No exposed pad — the 8-SOIC narrow body dissipates through the leads, so keep ambient airflow in mind if running near the 105°C limit at full data rate.

Frequently asked questions

Is ADUM3100BRZ-RL7 compatible with 5V logic?

Yes. The supply range of 3V to 5.5V on each side allows direct 5V logic interface without external level shifters.

What is the difference between ADUM3100BRZ and ADUM3100BRZ-RL7?

The ADUM3100BRZ-RL7 suffix indicates Tape & Reel packaging; the ADUM3100BRZ (without -RL7) is typically supplied in tubes. The electrical specifications are identical.
