Its 1 Mbps data rate and 3000 Vrms isolation target general-purpose isolation of slow serial buses, GPIO signals, and status lines where throughput beyond a few megabits isn't needed. The 50 ns max propagation delay and 10 ns pulse-width distortion keep timing predictable for UART, I²C (at standard mode), and discrete control signals. It won't handle full-speed SPI at 10 MHz or CAN FD at 5 Mbps — those need a faster variant in the family. ## 25 kV/µs CMTI — the motor-drive spec Common-mode transient immunity is a minimum 25 kV/µs. That's the figure that matters when this isolator sits between a noisy inverter phase leg and a low-voltage controller. A fast voltage step across the isolation barrier couples through parasitic capacitance; if the CMTI rating is too low, the output glitches. 25 kV/µs is adequate for most industrial drives and power supplies switching at 10–20 kHz with 600 V DC bus. For SiC or GaN stages switching at 100+ kV/µs, you'd step up to the ADuM family with 100+ kV/µs CMTI. ADUM1285ARZ-RL7 carries an active product status. It's a safe line-item for a production BOM with a multi-year horizon. The iCoupler series is a mature, high-volume platform from Analog Devices; second-sourcing within the family is straightforward if you need a pin-compatible alternate with a different speed grade or channel count. ROHS3 compliant — no exemption issues for EU or California markets. ## Supply and temperature — industrial range The 8-SOIC package with 3.90 mm width is a common footprint; no special reflow profile beyond standard lead-free solder.","metaTitle":"ADUM1285ARZ-RL7 Digital Isolator, 1 Mbps, 3000 Vrms, 8-SOIC","metaDescription":"ADUM1285ARZ-RL7 iCoupler digital isolator: 2 unidirectional channels, 1 Mbps data rate, 3000 Vrms isolation, -40°C to 125°C.

The 1 Mbps data rate limits throughput; a 10 MHz SPI clock would exceed the isolator's bandwidth.
