Introduction

AI Translation

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.
