ADUM3300CRWZ-RL

Overview

The ADUM3300CRWZ-RL is a three-channel digital isolator from Analog Devices, utilizing iCoupler technology to integrate high-speed CMOS circuitry with on-chip air-core transformer isolation. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides bidirectional signal transmission with a typical propagation delay of 32 ns and offers common-mode transient immunity of 25 kV/µs. It features an insulation rating of 2500 Vrms and functions reliably across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS technology with single-chip air-core transformer isolation for robust signal transmission.
• Provides bidirectional communication capability across three independent channels.
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial automation systems requiring reliable isolated communication
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics interfaces demanding high noise immunity

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing components. Confirm that the part number matches the exact channel count and bidirectional specification required for the design. Ensure compatibility with the intended operating voltage and temperature range before finalizing procurement decisions.

Selection Notes

Select this component when bidirectional data transfer is required across three isolated channels. It is suitable for designs needing high common-mode transient immunity and operation at data rates up to 90 Mb/s. Consider the SOIC-16 package constraints and power consumption characteristics relative to system thermal management capabilities.

Part Context

This device belongs to the ADuM330x series of digital isolators manufactured by Analog Devices. The series leverages proprietary iCoupler technology to replace traditional optocouplers, offering superior performance in speed, power efficiency, and reliability. The ADUM3300 variant specifically addresses applications requiring three-channel bidirectional isolation.

Replacement Considerations

Check for direct equivalents within the ADuM330x family, such as unidirectional variants like the ADUM3301 if bidirectional capability is not needed. Verify pinout compatibility and electrical specifications against alternative suppliers' offerings to ensure seamless integration without redesigning the PCB layout.
