ADUM1402CRW-RL

Overview

The ADUM1402CRW-RL is a quad-channel digital isolator utilizing iCoupler technology, housed in a 16-pin SOIC_W package. It supports a maximum data rate of 90 Mbps with typical rise and fall times of 2.5 ns. The device operates on supply voltages between 2.7 V and 5.5 V, providing 2500 Vrms isolation voltage and 25 kV/µs common-mode transient immunity.

Feature Summary

• Integrates four independent digital channels for bidirectional signal transmission
• Employs on-chip transformer-based magnetic coupling for galvanic isolation
• Provides high common-mode transient immunity to prevent noise-induced errors

Applications

• Industrial communication bus isolation
• Medical equipment signal interfacing
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel packaging and temperature grade. Ensure the component matches the required isolation voltage ratings and channel count for your circuit design before procurement.

Selection Notes

Select this component when high-speed data transmission up to 90 Mbps is required alongside robust galvanic isolation. Consider the 16-pin wide-body package for thermal performance and ease of PCB layout in dense industrial or medical applications.

Part Context

This part belongs to the ADuM140x family of quad-channel digital isolators. It shares architectural similarities with other members like the ADUM1400 and ADUM1401 but offers higher data rates suitable for demanding serial communication protocols.

Replacement Considerations

Official substitutes include ADUM1402ARWZ-RL and ADUM1402CRWZ-RL from Analog Devices. Verify pinout compatibility and electrical specifications before substitution.
