ADUM3301BRWZ

Overview

The ADUM3301BRWZ is a triple-channel digital isolator manufactured by Analog Devices Inc. It utilizes magnetic coupling technology to provide electrical isolation between circuits. The device supports unidirectional signal transmission with a data rate of 10 Mb/s. It operates within a supply voltage range of 3 V to 5.5 V and offers an insulation voltage of 2500 Vrms. Key performance parameters include a propagation delay of 32 ns, typical rise and fall times of 3 ns, and a common-mode transient immunity of 25 kV/µs. The component functions reliably across an operating temperature range of -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Provides three independent unidirectional signal channels for digital isolation
• Employs on-chip dual-coil technology for robust magnetic coupling isolation
• Delivers high common-mode transient immunity for noise-sensitive environments
• Ensures enhanced system-level electrostatic discharge reliability

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Power management circuits with isolated feedback loops
• Isolated gate drive interfaces for power switches

Procurement Notes

Verify the specific suffix (BRWZ) against official Analog Devices documentation to confirm the tape-and-reel packaging configuration and RoHS compliance status. Ensure that the selected variant matches the required channel directionality and data rate specifications for the target application design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring reliable isolation for up to three unidirectional signals at moderate data rates. Consider the 16-SOIC package dimensions for PCB layout constraints and thermal management requirements. Evaluate the 2500 Vrms insulation rating against the specific safety standards applicable to the end product. Confirm that the operating temperature range aligns with the environmental conditions expected during device deployment.

Part Context

This part belongs to the ADUM3301 series of triple-channel digital isolators from Analog Devices. It is distinct from bidirectional variants like the ADUM3300, which offer higher data rates but different channel configurations. The BRWZ suffix indicates a specific reel-based packaging option within the broader family of SOIC-16 packaged isolators designed for general-purpose isolation applications.
