Two-channel unidirectional isolator with 2500 Vrms rating
It supports a data rate up to 25 Mbps with typical rise/fall times of 2.5 ns, making it suitable for isolating SPI, UART, and general-purpose logic signals in industrial control, motor drives, and isolated power supplies. Propagation delay is 45 ns max in either direction, and pulse-width distortion is held to 3 ns max, preserving signal integrity for timing-critical links.
Channel topology and signal direction
The two channels are unidirectional with one input on side 1 and one input on side 2 (1/1 configuration). This means one channel carries data from side 1 to side 2, and the other from side 2 to side 1 — the natural arrangement for isolating a bidirectional serial bus like UART or a two-wire SPI link with separate data-in and data-out lines. If your application requires both channels in the same direction (two signals going from side 1 to side 2), the sibling ADUM3200CRZ-RL7 offers that 2/0 input count while keeping the same 25 Mbps data rate, 2500 Vrms isolation, and 45 ns propagation delay.
Housed in an 8-pin SOIC narrow-body package (3.90 mm width), the ADUM3201CRZ fits standard SOIC-8 land patterns and reflow profiles. No isolated DC-DC converter is integrated — the part provides signal isolation only. For applications needing isolated power, an external isolated converter or a part from the ADuM5xxx series with integrated power is required.
It is ROHS3 compliant, meeting current EU exemption requirements for lead-free soldering. No PCN or LTB has been issued for this order code.
