SI8920BC-IP

Overview

The SI8920BC-IP is a single-channel isolated analog amplifier from the Si8920 series, manufactured by Skyworks Solutions. It features a differential input and differential output configuration with a 1200 Vrms insulation voltage rating. The device operates on a supply voltage between 3 V and 5.5 V, consuming 4.2 mA of operating current. Key electrical parameters include a 950 kHz 3dB bandwidth, 200 uV input offset voltage, and 0.5% gain error. It is housed in an SOIC-16 package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for precision analog signal transmission across high-voltage barriers.
• Delivers high accuracy through low input offset voltage and minimal gain error specifications.
• Supports wide bandwidth operation suitable for dynamic signal processing applications.

Applications

• Industrial process control systems requiring isolated sensor interfacing
• Medical equipment needing patient isolation protection
• Power electronics monitoring circuits

Procurement Notes

Verify the specific suffix code against official Skyworks documentation to confirm pinout compatibility and functional equivalence. Ensure the procurement channel provides valid RoHS compliance data and moisture sensitivity level information prior to ordering.

Selection Notes

Select this component when a single-channel isolated amplifier with differential I/O is required. Compare the 1200 Vrms isolation rating and 950 kHz bandwidth against system requirements. Consider the SOIC-16 package size and thermal dissipation characteristics for PCB layout planning.

Part Context

This part belongs to the Si8920 family of isolated amplifiers. It shares core architectural similarities with other variants like the SI8920AC-IS but differs in specific electrical tolerances and input ranges defined by the manufacturer's coding scheme.

Replacement Considerations

Check for direct substitutes within the Si8920 series such as SI8920AC-IS or SI8920BD-IS. Verify that replacement parts match the required isolation voltage, bandwidth, and package dimensions before integration.
