ADUM1210BRZ

Overview

The ADUM1210BRZ is a dual-channel digital isolator utilizing Analog Devices iCoupler technology, which integrates high-speed CMOS logic with monolithic transformer technology on a single GaAs semiconductor chip. This component provides electrical isolation between circuits while transmitting digital signals. It features a data rate of 10 Mb/s and supports unidirectional signal transmission across two independent channels. The device operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 600 µA per channel. It offers an insulation voltage rating of 2500 Vrms and exhibits a propagation delay of 50 ns. The unit is housed in an 8-pin SOIC package and functions reliably within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS and monolithic transformer technology for compact isolation solutions
• Provides dual-channel unidirectional signal transmission with low power consumption
• Delivers robust electromagnetic compatibility through magnetic coupling isolation

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• General-purpose isolated interface circuits in embedded systems

Procurement Notes

Verify the specific ordering suffix and package variant against the official Analog Devices datasheet to ensure compatibility with design requirements. Confirm that the component meets all relevant safety certifications and regulatory standards applicable to the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when dual-channel isolation with moderate speed requirements is necessary. Consider the 10 Mb/s data rate and 50 ns propagation delay for timing-sensitive applications. Evaluate the 2500 Vrms insulation rating against system voltage requirements and ensure the SOIC-8 package fits the available PCB space constraints.

Part Context

The ADUM1210BRZ belongs to the ADUM121x series of digital isolators from Analog Devices. These devices are designed to replace traditional optocouplers by offering smaller size, lower power consumption, and improved reliability. The BRZ suffix indicates a lead-free RoHS-compliant version packaged in a standard SOIC-8 format suitable for surface-mount assembly.

Replacement Considerations

Direct substitutes may include other dual-channel iCoupler devices from Analog Devices such as the ADUM1201 or ADUM1211, depending on specific speed and voltage isolation requirements. Verify pinout compatibility and electrical specifications before substitution.
