5000 Vrms isolation in a 2-channel forward-direction isolator
The ADUM2210SRWZ is a 2-channel digital isolator from Analog Devices' iCoupler® family, using magnetic coupling to provide 5000 Vrms galvanic isolation. Both channels are unidirectional and oriented from Side 1 to Side 2 (2/0 input/side configuration), making it a forward-only isolation barrier — no reverse channel on this die. Data rate is rated at 1 Mbps, with a maximum propagation delay of 150 ns each direction and 40 ns pulse-width distortion.
25 kV/µs CMTI — what it means for motor-drive and inverter isolation
Common-mode transient immunity is rated at a minimum of 25 kV/µs.
1 Mbps data rate and 150 ns propagation delay — timing budget for the control loop
The 1 Mbps data rate limits the serial clock frequency to about 1 MHz for a single-bit SPI or UART isolation.
Package and temperature grade — industrial and outdoor deployment
The wide-body 16-SOIC package provides the creepage and clearance needed for 5000 Vrms reinforced isolation.
