Product details

Three-channel iCoupler for isolated signal paths

The Analog Devices ADUM1311BRWZ is a three-channel, unidirectional digital isolator from the iCoupler family, built around magnetic coupling technology. It delivers 3750Vrms of galvanic isolation across a 2/1 input-side-to-output-side channel split, making it a straightforward choice for breaking ground loops or protecting low-voltage logic on the isolated side of a motor drive, PLC I/O module, or medical sensor interface. Common-mode transient immunity is specified at a minimum 25kV/µs, which means the part holds its output state through the fast voltage slew events common in inverter-driven environments.

The supply range spans 2.7V to 5.5V on both sides, so the ADUM1311BRWZ can bridge a 3.3V MCU domain to a 5V field-side interface without an extra level translator. Surface-mount only; no through-hole option in this order code.

For tape-and-reel feed into automated assembly, the ADUM1311BRWZ-RL variant is the same die and package, just shipped on reel rather than tube. Stock the reel version if your pick-and-place line is set for 13-inch reels; the tube version works for hand-place or low-volume builds.

Frequently asked questions

What is the data rate of ADUM1311BRWZ?

The ADUM1311BRWZ is rated for a data rate of 10Mbps. Propagation delay is 50ns max, and pulse-width distortion is 5ns max, which keeps the signal integrity clean for SPI, UART, or general-purpose digital isolation up to that speed.

Is ADUM1311BRWZ RoHS compliant?

Yes, the ADUM1311BRWZ is ROHS3 compliant, meaning it meets the latest EU RoHS directive without exemptions for lead in solder or other restricted substances.

What is the equivalent of ADUM1311BRWZ?

The closest functional equivalent is the ADUM1311BRWZ-RL, which is the same die and package in tape-and-reel format. For a different channel direction configuration, the ADUM1300BRWZ offers three channels all in the same direction (3/0) but with a lower 2500Vrms isolation rating.
