Product details

10 Mbps dual-channel isolator for industrial signal isolation

It delivers 2500 Vrms isolation in a standard 8-SOIC package, with a 10 Mbps data rate that suits UART, SPI clock, and general-purpose signal isolation in industrial control, motor drives, and isolated power supply feedback paths.

The supply range spans 3V to 5.5V on both sides, so this single isolator bridges a 3.3V MCU domain to a 5V peripheral bus without an external level translator. Propagation delay is 50 ns max in either direction, and the 2.5 ns typical rise/fall time keeps signal integrity clean at 10 Mbps.

25 kV/µs CMTI — survives the motor-drive noise floor

Pulse-width distortion holds to 3 ns max, so the isolator does not add asymmetric delay to a PWM or encoder signal.

Frequently asked questions

What is the difference between ADUM3200BRZ-RL7 and ADUM3200CRZ-RL7?

The CRZ variant doubles the data rate to 25 Mbps and tightens propagation delay to 45 ns max. If your bus runs at 10 Mbps or slower, the BRZ is the cost-effective choice; the CRZ buys you headroom for faster SPI clocks or higher-throughput isolation.

Does ADUM3200BRZ-RL7 work with 5V logic?

Yes, the supply range is 3V to 5.5V on both sides, so it directly interfaces with 5V CMOS or TTL logic as well as 3.3V systems. No external level shifting is needed.

Is ADUM3200BRZ-RL7 compatible with 3.3V systems?

Yes, it operates from 3V to 5.5V, so 3.3V logic is well within the supply range. The inputs are unidirectional, so ensure the data direction matches the 2/0 input-side configuration.

Can ADUM3200BRZ-RL7 be used for SPI isolation?

It can isolate a single-direction SPI signal like SCK or MOSI at up to 10 Mbps. For full-duplex SPI you need two channels going opposite directions, which this part cannot do — it is 2/0 unidirectional only. Consider the ADUM1201 or a four-channel part for bidirectional SPI.
