What the ADUM2400CRWZ brings to a galvanic isolation barrier
The ADUM2400CRWZ is a 4-channel, unidirectional digital isolator from Analog Devices' iCoupler family. It uses magnetic coupling to transfer logic signals across a 5000 Vrms isolation barrier, enough for reinforced insulation in medical equipment and industrial motor drives. With a 90 Mbps data rate and 2.5 ns typical rise/fall times, it handles high-speed SPI, UART, and parallel bus isolation without adding significant skew—propagation delay is 32 ns max in either direction.
5000 Vrms isolation — the so-what for your BOM
The 5000 Vrms rating exceeds the 2500 Vrms of the ADUM3400CRWZ. The 25 kV/µs common-mode transient immunity prevents glitching during high dV/dt switching.
Supply range and channel direction
All four channels are unidirectional and oriented as 4 inputs on side 1 and 0 on side 2—meaning this variant is for data flowing in one direction only. If you need bidirectional channels, the ADUM2401BRIZ offers a 3/1 split, though at a lower 10 Mbps data rate.
Lifecycle and compliance
The ADUM2400CRWZ is Active and ROHS3 Compliant.
