ADUM3223ARZ-RL7

The ADUM3223ARZ-RL7 is a single-channel, high-speed digital isolator. It provides electrical isolation for one digital data path between two circuits at blazing-fast speeds, protecting them from ground loops, noise, and transient voltage spikes. This makes it ideal for demanding applications like:

• High-speed data acquisition systems
• Industrial automation and control systems
• Medical equipment
• Power supplies
• Instrumentation

Key Features:

• 5 kV RMS isolation voltage: Offers exceptional protection against even the highest voltages and transient spikes.
• Single-channel isolation: Supports data rates up to 150 Mbps, making it one of the fastest digital isolators available.
• Default low output: Simplifies design and reduces component count with active-low outputs by default.
• 50 kV/µs CMTI: Withstands incredibly 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: 5 kV RMS
• Data rate: 150 Mbps
• Output type: Open drain, active low
• CMTI: 50 kV/µs
• Input supply voltage: 3.3V or 5V
• Power consumption: Typically 20 mA
• 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 ADUM3223ARZ-RL7 on their website.

Comparison with ADUM1241ARZ-RL7:

• The ADUM3223ARZ-RL7 boasts a significantly higher isolation voltage (5 kV RMS vs. 2.5 kV RMS) and data rate (150 Mbps vs. 1 Mbps) compared to the ADUM1241ARZ-RL7.
• However, it has a higher power consumption (20 mA vs. 5 mA) and a larger, 16-lead SOIC package.
