ADUM6210CRSZ

Overview

The ADUM6210CRSZ is a dual-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides bidirectional signal isolation with a data rate of 100 Mbps and supports unidirectional operation. The device offers an insulation voltage of 3750 Vrms and a common-mode transient immunity of 25 kV/µs. It operates within a supply voltage range of 3.0 V to 5.5 V for both sides and delivers up to 150 mW of output power from the internal converter. The component is housed in a 20-pin SSOP package and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter to eliminate external transformer requirements
• Provides high-speed digital signal isolation at 100 Mbps data rates
• Features magnetic coupling technology for robust signal transmission
• Delivers regulated output voltage from the internal power converter

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power electronics control circuits
• Instrumentation interfaces

Procurement Notes

Verify the specific suffix (e.g., CRSZ) against the official Analog Devices datasheet to confirm pinout and electrical specifications. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the selected package matches the PCB footprint requirements. Cross-reference the revision level with the manufacturer's documentation to guarantee compatibility with existing designs.

Selection Notes

Select this component when a compact solution combining signal isolation and isolated power generation is required. It is suitable for applications demanding high common-mode transient immunity and fast data rates. Consider the thermal performance of the SSOP-20 package under maximum load conditions. Verify that the input and output voltage ranges align with the system logic levels before integration.

Part Context

This part belongs to the ADUM6210 series of isoPower digital isolators. It is designed to replace traditional discrete isolation solutions by integrating the power converter on-chip. The series is characterized by its small form factor and high reliability, making it a standard choice for modern interface designs where space and component count are critical constraints.

Replacement Considerations

Check for direct replacements such as the ADUM6211 if bidirectional communication is needed instead of unidirectional. Evaluate the ADUM6202 for applications requiring higher insulation voltage but lower data rates. Ensure any substitute maintains the same 20-SSOP footprint and pin configuration to avoid board redesign.
