Absolute Pressure Die (SM68A)

The SM5108E is an all silicon micro-machined, piezoresistive pressure sensing chip. The die is extremely small (0.69 mm x 0.69 mm) and has been optimized to provide the highest possible accuracy for a die of this size. Performance is achieved through careful resistor placement and mechanical configuration. The small die results in a significant cost saving when compared to larger sensor die.  This sensor is intended for high volume, cost sensitive applications, such as consumer tire pressure gauges or robust stable performance disposable pressure gauges. The SM5108E is available as an absolute pressure sensor in a full-scale range of 30, 60 & 100 PSI. It is designed to be mounted on ceramic or PC board substrates by high-volume OEM manufacturers.  Wafers are probed and visually inspected.
