• Power electronics interfaces where high common-mode transient immunity is critical.
• General-purpose digital isolation in mixed-signal circuits.

Procurement Notes

Verify the specific suffix BRQZ against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure the component meets RoHS3 standards as indicated in public listings. Confirm availability status directly with authorized distributors, as stock levels may vary. Cross-reference the manufacturer part number with the datasheet to validate channel count and isolation voltage ratings before procurement.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required in a compact surface-mount package. The ADUM140E0BRQZ is suitable for designs demanding high CMTI and moderate data rates up to 150Mbps. Consider the 16-SSOP footprint for space-constrained PCB layouts. Verify that the 3000Vrms isolation rating aligns with the system's safety requirements and regulatory standards.
