SI8920BC-AP

Overview

The SI8920BC-AP is an automotive-grade isolated analog amplifier manufactured by Skyworks Solutions. It features a specified linear input range of 62.5 mV and utilizes CMOS isolation technology with a 1200 Vrms insulation voltage. The device operates on a single supply voltage between 3 V and 5.5 V, consuming 4.2 mA of quiescent current. It provides differential input and output configurations within a wide-body SSOP-8 package. The component supports operation across an extended temperature range from -40°C to +125°C, ensuring reliability in demanding automotive environments.

Feature Summary

• Automotive-grade qualification for high-reliability applications
• CMOS-based digital isolation barrier for signal integrity
• Differential input and output architecture for noise rejection

Applications

• Current shunt measurement in automotive inverters
• Power supply monitoring systems
• Uninterruptible power supply (UPS) circuits

Procurement Notes

Verify the specific suffix AP indicates the wide-body SSOP-8 package configuration. Confirm automotive grade status through official Skyworks documentation. Check for end-of-life notices as related SI8920 variants show obsolescence trends. Ensure compatibility with existing PCB footprints for SOIC-8 or SSOP-8 packages before integration.

Selection Notes

Select this component when automotive certification is required for isolated signal conditioning. The 62.5 mV input range suits direct shunt resistor connections without external amplification. Compare against SI8920AC-IS for non-automotive needs or SI8922BB-IS for higher isolation voltage requirements. Evaluate power dissipation limits within the thermal constraints of the target enclosure design.
