ADUM1301BRWZ-RL

Overview

The ADUM1301BRWZ-RL is a triple-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates on a single 2.7V to 5.5V supply with channel configurations of 2Tx/1Rx or 1Tx/2Rx. Key electrical parameters include a data rate of 10 Mbps, isolation voltage of 2500 Vrms, and common-mode transient immunity of 25 kV/µs. Propagation delay is typically 32 ns with pulse width distortion under 3 ns. The device supports unidirectional signal transmission and functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates three independent digital isolation channels using monolithic transformer-based iCoupler technology for high-speed signal transmission.
• Provides robust noise immunity with high common-mode transient rejection capabilities suitable for noisy industrial environments.
• Features low power consumption and fast propagation delays optimized for efficient data communication across isolation barriers.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices.
• Medical equipment interfaces needing certified isolation for patient safety and signal integrity.
• Power electronics control circuits isolating gate drivers from logic controllers in motor drives.

Procurement Notes

Verify the specific suffix 'RL' indicates tape-and-reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. to ensure authenticity. Check RoHS compliance status against current regulatory requirements. Validate the SOIC-16 package dimensions against your PCB footprint specifications before finalizing procurement.

Selection Notes

Select this component when bidirectional isolation is not required, as it supports only unidirectional channels. Compare power consumption figures against alternatives if battery life is critical. Ensure the 10 Mbps data rate meets system timing requirements. Verify that the 2500 Vrms isolation rating satisfies the safety standards applicable to the target application environment.

Part Context

This part belongs to the ADuM1300/ADuM1301 series of triple-channel digital isolators. It represents a CMOS implementation of Analog Devices' proprietary iCoupler technology. The series offers a compact alternative to traditional optocouplers by integrating passive components directly onto the silicon die.
