Digital isolator for automotive and industrial isolation barriers
The ADUM120N1WBRZ from Analog Devices is a 2-channel, unidirectional digital isolator using iCoupler magnetic coupling technology. It provides 3000 Vrms isolation across the barrier, supports data rates up to 150 Mbps, and operates from a 1.8 V to 5.5 V supply. Rated for -40°C to 125°C and classified as automotive grade, this part is suited for safety isolation in electric vehicle battery management, traction inverter gate-drive interfaces, and industrial motor-drive control circuits where galvanic separation between low-voltage control and high-voltage power stages is required.
3000 Vrms isolation and 100 kV/µs CMTI — what they mean for the design
The 3000 Vrms isolation rating is specified in the datasheet. The 100 kV/µs CMTI exceeds the 75 kV/µs on the ADUM120N1BRZ-RL7 peer.
Automotive grade and extended temperature range
The automotive grade and -40°C to 125°C range suit under-hood and chassis-domain electronics. The 8-SOIC package with 3.90 mm body width fits standard footprints.
Sourcing and lifecycle
The ADUM120N1WBRZ carries an active lifecycle status and is ROHS3 compliant. It is available through independent distribution and quoted to order against an RFQ.
