Overview
The ADUM1253ASA+ is a dual-channel digital isolator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes iCoupler technology for signal isolation. The device operates with a single supply voltage range of 2.5 V to 5.5 V on both sides. It provides a typical propagation delay of 2 ns per channel. The isolation rating is 5000 Vrms for one minute. The package type is SOIC-8 with a wide-body configuration.
Feature Summary
- Dual-channel digital isolation using proprietary iCoupler technology
- High-speed data transmission capabilities with low propagation delay
- Integrated isolated power management support via isoPower architecture compatibility
Applications
- Industrial automation control systems
- Medical equipment signal isolation
- Power electronics gate drive interfaces
Procurement Notes
Verify authenticity through authorized distributors only. Check RoHS compliance status and lead times carefully as availability may vary. Ensure storage conditions meet moisture sensitivity level requirements before assembly. Confirm pinout alignment with existing PCB layouts during integration planning.
Selection Notes
Choose this component when high-speed bidirectional communication requires galvanic isolation between circuits operating at different potentials. Consider thermal performance and board space constraints due to the SOIC-8 package dimensions. Evaluate noise immunity needs against the specified common-mode transient rejection values.
Part Context
Part of the ADuM family focusing on robust digital isolation solutions. Designed to replace traditional optocouplers in modern applications requiring smaller form factors and higher reliability. Supports various industrial standards for safety and performance validation.
Replacement Considerations
Direct substitutes include ADUM1253ARZ and ADUM1253BRZ variants depending on temperature grade and packaging preferences. Cross-reference with ADuM1250 series for quad-channel alternatives if additional channels are required.
