SI8920AC-IPR

Overview

The SI8920AC-IPR is a single-channel isolated analog amplifier from the Si8920 series, manufactured by Skyworks Solutions Inc. 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 quiescent current of 4.2 mA. It offers a 3 dB bandwidth of 950 kHz and an input offset voltage of 200 uV. The output is differential, and it is housed in a 16-pin SOIC package.

Feature Summary

• Provides galvanic isolation for high-voltage measurement applications
• Supports differential input and output signal configurations
• Utilizes CMOS-based digital isolation technology

Applications

• Current shunt measurement
• Industrial process control systems
• Power supply monitoring

Procurement Notes

Verify the specific suffix 'IPR' against official Skyworks documentation to confirm reel packaging and tape-and-reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles defined in the datasheet. Confirm availability status as product lifecycle changes may affect long-term sourcing.

Selection Notes

Select this component when a single-channel isolated amplifier with 1200 Vrms isolation is required. The 950 kHz bandwidth suits moderate-speed applications. Compare gain error and offset voltage requirements against other Si8920 variants if higher precision or different isolation ratings are needed.

Part Context

This part belongs to the Si8920 family of isolated amplifiers designed for current shunt measurement. It complements other variants like SI8920AC-ISR and SI8920BD-IS within the same series, offering similar electrical performance but potentially differing in packaging or specific manufacturing revisions.

Replacement Considerations

Check Skyworks cross-reference tools for parametrically similar parts. Verify that any substitute maintains the 1200 Vrms isolation rating and 16-pin SOIC footprint.
