ADUM1200BR-RL7

Overview

The ADUM1200BR-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler technology to provide electrical isolation between circuits. It features a bidirectional architecture with 2/0 channel directionality, supporting data rates up to 25 Mbps. The device operates within a supply voltage range of 2.7 V to 5.5 V and offers an insulation voltage rating of 2500 Vrms. Key performance metrics include a maximum propagation delay of 50 ns, a typical rise/fall time of 3 ns, and a common-mode transient immunity of 25 kV/µs. It is housed in a narrow-body SOIC-8 package and supports operation across a temperature range of -40°C to +105°C.

Feature Summary

• Implements iCoupler technology combining high-speed CMOS and monolithic transformer capabilities for superior isolation performance compared to optocouplers.
• Provides bidirectional communication channels with integrated 3 V/5 V level translation functionality.
• Delivers precise timing characteristics including minimal pulse-width distortion and tight channel-to-channel matching.

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing certified galvanic isolation
• Power management circuits for monitoring and control
