Product details

150 Mbps, 4-channel iCoupler with 75 kV/µs CMTI

The ADUM142E0BRWZ is a 4-channel, unidirectional digital isolator from Analog Devices' iCoupler series, built on magnetic coupling technology. It delivers a 150 Mbps data rate with 13 ns typical propagation delay and 3 ns pulse-width distortion, making it a fit for high-speed isolation of SPI, UART, or CAN signals where timing margin matters. The 3750 Vrms isolation rating and 75 kV/µs common-mode transient immunity (CMTI) are the standout specs for motor-drive and inverter applications where fast voltage transients on the isolation barrier can otherwise corrupt data.

Supply range and channel configuration

The channel split is 2 inputs on side 1 and 2 on side 2 — a balanced bidirectional arrangement that suits half-duplex buses or mixed-direction control signals.

Frequently asked questions

Can ADUM142E0BRWZ be used for SPI isolation?

Yes. The 150 Mbps data rate and 13 ns propagation delay are fast enough for SPI clock rates up to tens of MHz. The unidirectional channels match SPI's signal direction (MOSI, MISO, SCLK, CS), though you will need one device per direction or a part with bidirectional channels if your design requires a shared bus.
