DESCRIPTION
The SM7331 is a digital, ultra-low pressure MEMS sensor offering
state-of-the-art pressure transducer technology and CMOS mixed
signal processing technology to produce a digital, fully conditioned,
multi-order pressure and temperature compensated sensor in JEDEC
standard SOIC-16 package with a dual vertical or a dual horizontal
porting option. It is available in a differential pressure configuration.
Combining the pressure sensor with a signal-conditioning ASIC in a
single package simplifies the use of advanced silicon micro-machined
pressure sensors. The pressure sensor can be mounted directly on a
standard printed circuit board and a high level, calibrated pressure
signal can be acquired from the digital interface. This eliminates the
need for additional circuitry, such as a compensation network or
microcontroller containing a custom correction algorithm.
The SM7331 is shipped in sticks or tape & reel.
