Product details

25 Mbps digital isolator with magnetic coupling

The Analog Devices ADUM3471CRSZ is a 4-channel, general-purpose digital isolator from the iCoupler series, using magnetic coupling technology to transmit digital signals across a 2500 Vrms isolation barrier. It supports a data rate of 25 Mbps with unidirectional channel configuration (3 inputs on side 1, 1 input on side 2), making it suitable for isolating SPI, UART, or general-purpose logic signals in industrial and power applications.

Propagation delay and transient immunity

The common-mode transient immunity of 25 kV/µs (minimum) ensures reliable operation in noisy industrial environments where fast voltage transients across the barrier could otherwise corrupt data. Rise and fall times are typically 2.5 ns, keeping signal integrity clean at 25 Mbps.

Frequently asked questions

What is the data rate of ADUM3471CRSZ?

The ADUM3471CRSZ supports a data rate of 25 Mbps.

What are the alternatives to ADUM3471CRSZ?

Within the iCoupler family, the ADUM3470ARSZ offers a lower data rate of 1 Mbps with 4/0 input configuration, while the ADUM3400CRWZ runs at 90 Mbps with 4/0 inputs. The ADUM2401BRIZ provides 5000 Vrms isolation at 10 Mbps with the same 3/1 input split. None are pin-compatible — each uses a different package or channel assignment.
