DESCRIPTION
The SM5420E is a small outline SO8 packaged pressure sensor that
incorporates SMI’s new SM5108E MEMS piezoresistive pressure
sensing die. The SM5420E has been optimized to provide the highest
possible stability for a package of this size. Performance is achieved
through careful resistor placement and mechanical configuration
along with advanced MEMS processing.
The packaged sensor is intended for high volume applications where
cost is a critical factor, such as consumer and automotive products.
The SM5420E is available as an absolute pressure sensor in full-scale
ranges of 30, 60 and 100PSI. It is designed to be surface-mounted on
substrates by high-volume OEM manufacturers.
The SM5420E is available in a ported and non-ported option. The package
is designed to be immersed in the media that is measured. The standard
configuration offers a protective gel over the die. The SM5420E is shipped
tape & reel.
