Performance

Two models of this product are available depending on demands in target application. The lower range model has a lower scale factor (higher resolution) and better performance in regards to noise. Both models have DC response, with low bias drift, and incorporate a temperature sensor. A SPI interface enables easy and effective communication between customer application and sensor. A number of functions are available through the digital SPI interface including advanced self diagnostics.
