ADUM1310ARWZ

Digital Isolators Overview

The ADUM1310ARWZ is a triple-channel digital isolator utilizing Analog Devices iCoupler technology. It features magnetic coupling isolation with a 3750 Vrms insulation voltage and supports data rates up to 1 Mbps. The device operates on a single power supply ranging from 2.7 V to 5.5 V, drawing typical currents of 1.2 mA or 2.4 mA per channel depending on the speed. It provides unidirectional signal transmission in a 16-lead SOIC package, ensuring high common-mode transient immunity of 25 kV/µs.

Digital Isolators Feature Summary

• Integrates three independent isolation channels using patented iCoupler magnetic coupling technology
• Features programmable default output states for inputs when local power is absent
• Includes patented refresh circuitry to maintain DC correctness during input hold conditions
• Provides robust performance with high common-mode transient immunity

Digital Isolators Applications

• General-purpose multi-channel isolation
• SPI interface and data converter isolation
• RS-232, RS-422, and RS-485 transceiver isolation
• Industrial fieldbus isolation

Digital Isolators Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and orientation. Ensure the component matches the required isolation voltage rating of 3750 Vrms for your application safety standards. Confirm RoHS compliance status through the manufacturer's current certification documents before finalizing procurement specifications.

Digital Isolators Selection Notes

Select this component when three isolated bidirectional or unidirectional channels are required within a compact footprint. It is suitable for systems needing voltage translation between 2.7 V and 5.5 V domains. Consider its low power consumption compared to optical couplers and its ability to eliminate current transfer ratio uncertainties inherent in LED-based solutions.

Digital Isolators Part Context

This part belongs to the ADUM131x series of digital isolators from Analog Devices. These devices replace traditional optocouplers by integrating high-speed CMOS logic with monolithic air-core transformer technology. The series offers improved reliability, higher channel density, and consistent performance across temperature ranges without the degradation associated with optical components.

Digital Isolators Replacement Considerations

The ADUM1301ARWZ is a confirmed substitute within the same family, offering similar functionality but with a lower basic insulation rating of 2500 Vrms compared to the 3750 Vrms of the ADUM1310ARWZ.
