DESCRIPTION
The SM1X21 Series is a digital, medium pressure MEMS sensor
family 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 both dual vertical
and dual horizontal porting options. It is available in both compound
gage or differential pressure configurations. With the dual porting, a
vacuum-gage measurement is possible to minimize altitude errors
due to changes in ambient pressure.
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.
Customer-specified pressure ranges and supply voltages are
available.
The SM1X21 Series is shipped in sticks or tape & reel.
