Overview
The ADUM7241ARZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology. It provides 1000Vrms isolation voltage and supports data rates up to 1Mbps. The device features 15kV/µs common-mode transient immunity (CMTI). It operates within an extended temperature range of -40°C to +105°C. The component is housed in an 8-SOIC package with a width of 3.90mm.
Feature Summary
- Combines high-speed CMOS logic with monolithic air-core transformer technology for signal transmission.
- Provides robust electrical isolation between isolated circuits without optical components.
- Offers high common-mode transient immunity to prevent false triggering in noisy environments.
Applications
- Industrial automation systems requiring galvanic isolation
- Medical equipment needing safe patient isolation
- Power metering applications with high-voltage separation
Procurement Notes
Verify the specific suffix ARZ indicates the tube packaging variant when ordering. Confirm the manufacturer part number matches exactly to ensure compatibility with design specifications. Check current availability status as supply may be limited or subject to allocation. Ensure the intended application environment falls within the specified operating temperature range.
Selection Notes
Select this component when dual-channel isolation is required with moderate data speeds. Consider the 1000Vrms rating for basic insulation requirements. Evaluate the 8-SOIC footprint against available PCB space. Compare CMTI performance against system noise levels to ensure reliable operation.
Part Context
This device belongs to the ADuM724x family of digital isolators. It shares the iCoupler magnetic coupling architecture with other members like the ADUM7240. The family focuses on replacing optocouplers with solid-state alternatives for improved reliability and speed.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Verify pinout and isolation ratings before considering any alternative devices.
