ADUM3300ARWZ

Overview

The ADUM3300ARWZ is a triple-channel digital isolator utilizing Analog Devices iCoupler technology, which integrates high-speed CMOS circuitry with monolithic air-core transformer coils. It provides unidirectional signal isolation in a 16-lead SOIC package. Key electrical specifications include a data rate of 1 Mb/s, an insulation voltage of 2500 Vrms, and a common-mode transient immunity of 25 kV/µs. The device operates within a supply voltage range of 2.7 V to 5.5 V, with typical quiescent currents of 1.1 mA and 2.4 mA for the two power domains. Propagation delay is specified at 65 ns, with rise and fall times of 3 ns. It functions reliably across an industrial temperature range from -40°C to +105°C.

Feature Summary

• Integrates three independent unidirectional signal channels using proprietary magnetic coupling technology.

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal interfaces
• General-purpose isolated communication links

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'ARWZ' matches the required wide-body SOIC-16 package and lead-free RoHS compliance status. Check current availability as supply may be limited or subject to factory special orders. Ensure storage conditions account for moisture sensitivity classification prior to soldering.

Selection Notes

Select this component when three isolated bidirectional or unidirectional logic paths are required within a single package footprint. It serves as a robust alternative to optocouplers, offering superior lifetime stability and lower power consumption. Consider the 1 Mb/s data rate limit and 2500 Vrms isolation barrier when designing circuits that demand high reliability without the degradation associated with LED-based isolation technologies.

Part Context

This part belongs to the ADUM330x series of triple-channel digital isolators. It represents a class of devices designed to replace traditional optocouplers by eliminating light-emitting diodes and phototransistors. The series leverages silicon-based magnetic coupling to provide consistent performance over time, addressing the wear-out mechanisms inherent in optical isolation components used in long-life industrial applications.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the ADUM3301ARWZ (bidirectional) and ADUM3302ARWZ (mixed directionality). Verify channel directionality requirements before substitution, as functional differences exist between these variants despite identical packaging and electrical ratings.
