Si8931/32 Data Sheet
Isolated Amplifier for Voltage Measurement
The Si8931/32 is a galvanically isolated analog amplifier optimized for voltage sensing. Its 2.5
V input range is ideal for isolated voltage sensing applications. The output is a differential
analog signal (Si8931) or single-ended signal (Si8932) that is proportional to the input voltage.
The Si8931/32 provides excellent linearity with low offset and gain drift to ensure that accuracy
is maintained over the entire operating temperature range. Exceptionally high common-mode
transient immunity means that the Si8931/32 delivers accurate measurements even in the
presence of high-power switching as is found in motor drive systems and inverters.
The Si8931/32 isolated voltage sensing amplifier utilizes Silicon Labs’ proprietary isolation
technology. It supports up to 5.0 kVrms withstand voltage per UL1577. This technology enables
higher performance, reduced variation with temperature and age, tighter part-to-part matching,
and longer lifetimes compared to other isolation technologies.
Applications:
• Industrial, HEV and renewable energy inverters
• AC, Brushless, and DC motor controls and drives
• Variable speed motor control in consumer white goods
• Isolated switch mode and UPS power supplies
• General industrial data acquisition and sensor interface
• Automotive onboard chargers, battery management systems, and charging stations
Safety Approvals (pending):
• UL 1577 recognized
• Up to 5000 Vrms for 1 minute
• CSA approval
• IEC 60950-1, 62368-1 (reinforced insulation)

1.1 Automotive-Grade OPNs
Automotive-grade devices are built using automotive-specific flows at all steps in the manufacturing process to ensure robustness
and low defectivity. These devices are supported with AIAG-compliant Production Part approval Process (PPAP) documentation, and
feature International Material Data System (IMDS) and China Automotive Material Data System (CAMDS) listing. Qualifications are
compliant with AEC-Q100, and a zero-defect methodology is maintained throughout definition, design, evaluation, qualification, and
mass production steps.
Automotive-Grade Ordering Part Numbers are in development and will be made available. Please contact your local Silicon Labs sales
representative for further information.
