Product details

1 Mbps isolation with onboard DC-DC

2500 Vrms isolation and 25 kV/µs CMTI

Isolation is rated at 2500 Vrms, adequate for basic insulation in 240 VAC equipment and for functional isolation in higher-voltage systems where reinforced isolation is not required. The common-mode transient immunity minimum of 25 kV/µs means the part holds data integrity through fast voltage transients — a key spec for motor-drive, inverter, and switched-mode power supply applications where the ground plane jumps at high dv/dt. The magnetic coupling technology keeps rise and fall times at 2.5 ns typical, so signal integrity stays clean across the isolation barrier without excessive edge-rate filtering.

Frequently asked questions

What is the maximum data rate for ADUM5211ARSZ-RL7?

The maximum data rate is 1 Mbps. If your design requires faster isolation — for example, a 10 Mbps SPI bus or high-speed encoder feedback — the pin-compatible ADUM5211CRSZ-RL7 runs at 100 Mbps with the same 2500 Vrms isolation and integrated power.

Does ADUM5211ARSZ-RL7 require an external oscillator?

No. The integrated isolated power supply uses an internal oscillator — no external clock or crystal is needed for the DC-DC converter function. The data channels are driven by the input-side logic levels directly.
