Key electrical parameters include a data rate of 150 Mb/s, an insulation voltage of 3750 Vrms, and a propagation delay of 15 ns. The device operates on a supply voltage range of 1.7 V to 5 V, drawing 11 mA of working power supply current. It supports SPI protocols and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four independent isolation channels using proprietary iCoupler magnetic coupling technology for high-speed data transmission.
• Provides robust galvanic isolation with a rated insulation voltage of 3750 Vrms to protect sensitive circuitry.
• Supports unidirectional signal flow across two input and two output channels, suitable for standard logic interfaces.

Digital Isolators Applications

• Industrial automation systems requiring isolated communication between microcontrollers and peripheral devices.
• Medical equipment needing reliable galvanic separation for patient safety and noise immunity.
• Automotive electronics utilizing CAN or LIN bus networks where signal integrity is critical.

Digital Isolators Procurement Notes

Verify the specific suffix 'WZ' indicates the SOIC-16 wide package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the component meets humidity sensitivity level requirements for your assembly process. Cross-reference the exact part number against the latest Analog Devices datasheet to confirm pinout and electrical specifications match your design needs.

Digital Isolators Selection Notes

Select this component when a quad-channel isolator with 3750 Vrms rating is required. It is appropriate for designs needing 150 Mb/s data rates with low propagation delay. Consider the 1.7 V to 5 V supply range for compatibility with various logic families. The unidirectional nature suits applications where signal flow is strictly one-way across the isolation barrier.
