Product details

Six-channel unidirectional isolation at 150 Mbps

It provides 5000 Vrms isolation across the barrier, with a data rate of 150 Mbps and typical rise/fall times of 2.5 ns. The 5/1 input split (five channels on side 1, one on side 2) suits applications like SPI bus isolation, where multiple data lines and a single chip-select need separation.

5000 Vrms and 75 kV/µs CMTI — isolation for noisy environments

The 5000 Vrms isolation rating covers reinforced insulation requirements for industrial motor drives, medical equipment, and grid-tied power converters. The minimum common-mode transient immunity of 75 kV/µs means the part rejects fast voltage spikes across the barrier — a spec that matters when a SiC or IGBT switch transitions at tens of kV/µs. Propagation delay is symmetrical at 13 ns max for both low-to-high and high-to-low transitions, with pulse-width distortion held to 4.5 ns max, so the output pulse width stays close to the input. That timing consistency keeps the bus margin intact in a 150 Mbps SPI link.

For dual-sourcing or a lower channel count, the ADUM251N0BRIZ (5-channel, same 150 Mbps and 5000 Vrms rating) is a pin-compatible alternative within the same iCoupler family.

Package and temperature grade

Housed in a 16-pin SOIC wide-body (7.50 mm width) package, surface-mount. The wide-body SOIC provides the creepage distance needed to sustain the 5000 Vrms rating across the isolation barrier.

Frequently asked questions

Is ADUM261N0BRIZ unidirectional?

Yes, all six channels are unidirectional. Five channels carry signals from side 1 to side 2, and one channel runs from side 2 to side 1, making it suitable for SPI or similar unidirectional data buses.

What is the data rate of ADUM261N0BRIZ?

The ADUM261N0BRIZ supports a data rate of 150 Mbps per channel, with typical rise/fall times of 2.5 ns and propagation delay of 13 ns max.

Can ADUM261N0BRIZ be used for I2C isolation?

No, the ADUM261N0BRIZ has unidirectional channels only, while I2C requires bidirectional data lines. For I2C isolation you would need a part with bidirectional channel support or an external direction-control circuit.

When sourcing ADUM261N0BRIZ, what's the closest functional alternative?

The ADUM251N0BRIZ is a 5-channel variant in the same iCoupler family, with identical 150 Mbps data rate, 5000 Vrms isolation, and 75 kV/µs CMTI. It uses a 4/1 input split (four on side 1, one on side 2) instead of the 5/1 split on the ADUM261N0BRIZ. Both are pin-compatible in the 16-SOIC wide-body package.
