ADUM1100URZ-RL7

The ADUM1100URZ-RL7 is a quad-channel digital isolator. It provides electrical isolation for four independent data paths between two digital circuits, protecting them from ground loops, noise, and transient voltage spikes. This makes it suitable for various applications, including:

• Industrial automation and control systems
• Medical equipment
• Power supplies
• Instrumentation
• Data acquisition systems

Key Features:

• 2.5 kV RMS isolation voltage per channel: Offers robust protection against high voltages and transient spikes.
• Four independent data channels: Each channel supports data rates up to 15 Mbps.
• Default low output: Simplifies design and reduces component count with active-low outputs by default.
• 25 kV/µs CMTI: Withstands high-speed transients without data errors.
• UL 1577 and IEC 60601 safety certifications: Suitable for safety-critical applications.
• 16-lead SOIC package: Compact size for easy integration into space-constrained designs.

Technical Specifications:

• Isolation voltage: 2.5 kV RMS per channel
• Data rate: 15 Mbps per channel
• Output type: Open drain, active low
• CMTI: 25 kV/µs
• Input supply voltage: 3.3V or 5V
• Power consumption: Typically 8 mA per channel
• Operating temperature range: -40°C to +125°C

Additional Details:

• Similar to other Analog Devices isolators, it utilizes transformer-based isolation technology for excellent noise rejection and signal integrity.
• It comes in two versions: default low output (RL7) and default high output (RH7).
• Analog Devices offers a comprehensive datasheet and application note for the ADUM1100URZ-RL7 on their website.
