The ADUM131E1BRWZ is a 3-channel, unidirectional digital isolator from Analog Devices' iCoupler series, built on magnetic coupling technology. It delivers 150 Mbps per channel with 13 ns propagation delay and 3 ns pulse-width distortion.
75 kV/µs CMTI — why it matters for motor drives and inverters
Common-mode transient immunity of 75 kV/µs (minimum) means this isolator holds its logic state across the barrier. The 2.5 ns typical rise/fall time also helps maintain signal integrity on high-speed lines.
The 2/1 input split (two channels from side 1 to side 2, one from side 2 to side 1) covers common isolation patterns like SPI or UART. No isolated power is generated on-chip.
Package and temperature grade — industrial and automotive fit
Housed in a 16-pin SOIC with 7.50 mm body width, the ADUM131E1BRWZ provides the creepage distance needed for 3750 Vrms isolation. ROHS3 compliant and lead-free.
