ADUM1310BRWZ

Digital Isolators Overview

The ADUM1310BRWZ is a triple-channel digital isolator from Analog Devices, utilizing iCoupler technology which combines high-speed CMOS circuitry with monolithic air-core transformer isolation. It provides robust signal transmission across isolation barriers with a rated insulation voltage of 3750 Vrms and a common-mode transient immunity (CMTI) of 25 kV/µs. The device supports data rates up to 10 Mbps and operates within a supply voltage range of 2.7 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 50 ns, typical rise and fall times of 2.5 ns, and a pulse width distortion of 5 ns. It functions in an unidirectional configuration with a 1:2 channel split (one input side, two output side). The component is housed in a 16-lead SOIC package (0.295 inch width) and is rated for operation between -40°C and +105°C.

Digital Isolators Feature Summary

• Integrates three independent digital channels using magnetic coupling via monolithic air-core transformers for galvanic isolation.
• Features programmable default output states to ensure defined logic levels at power-up or fault conditions.
• Provides high common-mode transient immunity of 25 kV/µs to maintain signal integrity in noisy environments.
• Supports bidirectional communication flexibility through configurable channel directionality within the triple-channel architecture.

Digital Isolators Applications

• Industrial automation systems requiring isolated communication between microcontrollers and peripheral devices.
• Medical equipment needing reliable galvanic isolation for patient safety and signal accuracy.
• Power electronics control circuits where high-voltage noise immunity is critical for gate drive signals.
• Data acquisition systems isolating analog-to-digital converter interfaces from high-noise digital domains.

Digital Isolators Procurement Notes

Verify the specific suffix 'BRWZ' to confirm the package type and temperature grade. Ensure the ordering part number matches the required tape-and-reel or tube packaging format if applicable. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for any recent product change notices that may affect pinout or electrical characteristics. Validate that the supplier provides genuine components with traceable manufacturing dates.

Digital Isolators Selection Notes

Select this component when three isolated channels are required with moderate data rates up to 10 Mbps. Consider the 3750 Vrms isolation rating for basic insulation requirements in industrial applications. Evaluate the 1:2 channel configuration against system topology needs. Compare power consumption figures against battery-operated constraints if applicable. Ensure the SOIC-16 footprint fits the PCB layout constraints compared to smaller packages.

Digital Isolators Part Context

The ADUM1310 belongs to the ADUM131x family of iCoupler digital isolators from Analog Devices. This series leverages silicon dioxide insulation layers and copper coils to replace traditional optocouplers. The family offers variations in channel count and data rate, with the ADUM1310 providing a balance of speed and isolation performance. It serves as a direct replacement for legacy optocoupler solutions in space-constrained designs.

Digital Isolators Replacement Considerations

The ADUM1310ARWZ is a related variant within the same family, potentially differing in temperature grade or initial testing specifications. Verify compatibility with existing board layouts when substituting between ADUM1310 variants. Cross-reference datasheet updates for any changes in recommended operating conditions. Ensure that alternative parts meet the same 3750 Vrms isolation and 25 kV/µs CMTI standards.
