· For Extremely High-Volume Applications

· Ultra-Small, Low Cost OEM Pressure Die

DESCRIPTION

The SM5108 is a extremely small (0.65 mm x 0.65 mm) silicon micromachined piezoresistive pressure sensing chip that has been optimized to provide the highest possible accuracy for a die of this size. This 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. Over 24,000 die come on a 150 mm wafer.

This sensor is intended for high volume applications where cost is a critical factor, such as consumer tire pressure gauges or disposable pressure gauges. The SM5108 is available as an absolute pressure sensor in full-scale ranges of 15 PSI, 30 PSI, 60 PSI, and 150 PSI. It is designed to be mounted on ceramic or PC board substrates by high volume OEM manufacturers.
