Product details

25 Mbps dual-channel isolator for industrial interfaces

It delivers a data rate of 25 Mbps with a maximum propagation delay of 45 ns and pulse-width distortion limited to 3 ns, making it suitable for isolating SPI, UART, and general-purpose digital signals in industrial automation, motor drives, and power-supply control loops. The 2500 Vrms isolation rating and 25 kV/µs minimum common-mode transient immunity support reliable operation in noisy environments with ground-potential differences.

Package and footprint

Surface-mount assembly with conventional reflow profiles works fine—no exposed pad to stitch.

Frequently asked questions

What is the difference between ADUM3201CRZ and ADUM3201BRZ?

The ADUM3201CRZ and ADUM3201BRZ are speed-graded variants in the same iCoupler family. The CRZ grade is rated for 25 Mbps data rate, while the BRZ grade is rated for a lower data rate (typically 10 Mbps). Both share the same 2-channel unidirectional architecture, 2500 Vrms isolation, and 8-SOIC package. The CRZ is the faster option for applications needing higher throughput.

Is ADUM3201CRZ-RL7 suitable for I2C isolation?

No, the ADUM3201CRZ-RL7 has unidirectional channels, which cannot handle the bidirectional data line (SDA) of I2C. For I2C isolation, look at the ADUM1250 or ADUM1251, which provide bidirectional isolation for the I2C bus.

What is the closest pin-compatible alternative to ADUM3201CRZ-RL7?

Within the iCoupler family, the ADUM3201BRZ-RL7 is pin-compatible and shares the same 8-SOIC footprint, 2500 Vrms isolation, and supply range, but is rated for a lower data rate (typically 10 Mbps). The ADUM3200CRZ-RL7 is also pin-compatible but offers two channels in the same direction (Side 1/Side 2: 2/0) instead of the 1/1 configuration of the ADUM3201CRZ-RL7.
