SM6841 Ultra Small Absolute Pressure Sensor With mV Output
The SM6841 is a small outline SO-8 packaged pressure sensor that incorporates SMI's new piezoresistive pressure sensing die.
This sensor is intended for high volume applications where cost is a critical factor. The SM6841 is available as an absolute pressure sensor in full-scale range of 30 psi (200 kPa) and 100 psi (700 kPa). It is designed to be surface-mounted on ceramic or PCB substrates by high volume OEM manufacturers.
The SM6841 is available in a non-ported, centered hole configuration to be used for sensing general environmental pressure or measure pressure in a manifold configuration with an O-ring seal.
The standard configuration offers a protective gel over the die. A non-gel version is also available for high volumes where the maximum stability is required, such as barometric weather station sensing applications. The SM6841 is shipped tape & reel.
