SI8920BC-IPR

Overview

The SI8920BC-IPR is a single-channel isolated analog amplifier from the Si8920 series manufactured by Skyworks Solutions. It features a 1200 Vrms isolation voltage and CMOS isolation technology. The device operates on a supply voltage between 3 V and 5.5 V with a typical current consumption of 4.2 mA. Key electrical parameters include a 3 dB bandwidth of 950 kHz, an input offset voltage of 200 uV, and a gain error of 0.5%. It provides differential input and output capabilities with a maximum output current of 3.8 mA per channel. The component is housed in an SOIC-16 package and supports surface mount installation.

Feature Summary

• Provides galvanic isolation for precision analog signal transmission across potential barriers
• Utilizes CMOS-based isolation architecture to ensure high reliability and low power consumption
• Supports differential input and output configurations for enhanced noise immunity

Applications

• Industrial process control systems requiring precise sensor signal conditioning
• Medical equipment needing isolated measurement channels for patient safety
• Power electronics monitoring circuits for high-voltage environments

Procurement Notes

Verify the specific suffix 'IPR' indicates tape and reel packaging rather than tube packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check for end-of-life notices as some variants in this series have been marked obsolete. Ensure moisture sensitivity level handling procedures are followed during assembly.

Selection Notes

Select this component when a single-channel isolated amplifier with 1200 Vrms isolation is required. Compare against other Si8920 variants based on specific gain error and bandwidth needs. Consider the SOIC-16 package size for PCB layout constraints. Verify that the 3 V to 5.5 V supply range matches the system design requirements.

Part Context

This part belongs to the Si8920 family of isolated analog amplifiers designed for high-performance applications. The family includes various packages and insulation ratings to suit different design needs. The SI8920BC-IPR specifically offers a balance of bandwidth and accuracy within this lineup.

Replacement Considerations

Check for direct substitutes within the Si8920 series such as SI8920AC-IS or SI8920BC-IS. Verify pin compatibility and electrical specifications before substitution. Consult official Skyworks documentation for approved replacement parts.
