The SI8931D-AS4 galvanically isolated analogue amplifier has a 2.5 V input range optimised for isolated voltage detection applications. The output is a differential analogue signal proportional to the input voltage or a single-ended signal. Excellent linearity, low offset and low gain drift maintain accuracy over the full operating temperature range. Extremely high common-mode transient immunity ensures that the Si8931/32 provides accurate measurements even when high power switching occurs in motor drive systems and inverters.
