Product details

5000Vrms isolation in a 16-SOIC — the ADUM2211TRIZ

It supports data rates up to 10Mbps with 50ns max propagation delay and 3ns pulse-width distortion, making it a fit for isolating SPI, UART, or general-purpose logic signals in industrial and automotive environments.

25kV/µs CMTI — why it matters for motor drives and inverters

Common-mode transient immunity is rated at 25kV/µs minimum. In a motor-drive or inverter application, fast-switching IGBTs or SiC FETs can slam the ground reference with several kV/µs of common-mode noise. If the isolator's CMTI is too low, the output can glitch or latch. The ADUM2211TRIZ's 25kV/µs rating keeps the data path clean across the isolation barrier in those environments.

For a production BOM, this part does not introduce a single-source obsolescence risk today.

Package and footprint notes for the layout engineer

No exposed pad — all dissipation goes through the leads. The 5000Vrms isolation rating relies on the creepage distance the wide SOIC provides; maintain the keep-out zone under the package on inner layers to preserve the isolation barrier.

Frequently asked questions

Is ADUM2211TRIZ compatible with both 3.3V and 5V supplies?

Yes. Both sides of the isolation barrier can run from the same supply or different supplies within that range.

Does ADUM2211TRIZ have an isolated DC-DC converter?

No. The ADUM2211TRIZ does not include an isolated DC-DC converter — it is a signal isolator only. For an isolated power rail, you need a separate isolated DC-DC module or a part like the ADuM540x series that integrates both signal isolation and an isolated power converter.

What is the difference between ADUM2211TRIZ and ADUM2210TRIZ?

The ADUM2211TRIZ has two channels with a 1/1 input-to-output direction configuration (one channel each way). The ADUM2210TRIZ is a single-channel device. Both share the same 5000Vrms isolation, 10Mbps data rate, and 16-SOIC package. Choose the ADUM2210TRIZ when you need only one isolation channel; the ADUM2211TRIZ when you need bidirectional isolation in a single package.

Can ADUM2211TRIZ be used in medical isolation applications?

The 5000Vrms isolation rating is suitable for many medical equipment applications that require reinforced insulation per IEC 60601, but the part is not listed as a medical-grade or AEC-Q100 qualified device. Verify the specific isolation voltage, creepage, and clearance requirements of your medical standard before specifying.
