ADUM152N1BRZ-RL7

Digital Isolators Overview

The ADUM152N1BRZ-RL7 is a robust five-channel digital isolator from Analog Devices, housed in a 16-pin SOIC package. It operates with a unidirectional signal flow and supports data rates up to 150 Mb/s. The device provides an insulation voltage of 3000 Vrms using magnetic coupling technology. It functions within a supply voltage range of 1.7 V to 5.5 V, drawing a typical operating current of 13.7 mA. Key electrical characteristics include a propagation delay of 7.2 ns, rise and fall times of 2.5 ns, and a pulse width distortion of 500 ps. It withstands a common-mode transient immunity of 75 kV/µs and operates reliably across a temperature range of -40°C to +125°C.

Digital Isolators Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the exact channel configuration and polarity requirements for your design. Check for any recent product change notifications that may affect specifications or availability.

Digital Isolators Selection Notes

Select this component when five unidirectional isolated channels are required in a single package. Compare against other ADuM152 variants based on packaging type (tube vs. reel) and specific polarity configurations. Consider the 150 Mb/s data rate limit and 3000 Vrms isolation rating against system requirements. Evaluate power consumption and thermal performance within the -40°C to +125°C operating range.

Digital Isolators Part Context

This device belongs to the ADuM152N family of digital isolators from Analog Devices. It utilizes iCoupler technology to integrate transformer and semiconductor processes on a single silicon chip. The family offers various channel counts and polarity options to suit different interface needs while maintaining high reliability and low power consumption.

Digital Isolators Replacement Considerations

Check for ADUM152N0BRZ-RL7 if a 5/2 channel configuration is acceptable instead of 4/1. Verify pinout compatibility before substituting with other ADuM152 series parts. Consult official cross-reference guides for direct replacements with identical electrical characteristics.
