DESCRIPTION
The SM6844 Series is an absolute pressure MEMS sensor family offering
state-of-the-art pressure transducer technology and CMOS mixed signal
processing technology to produce an analog, fully conditioned, pressure
and temperature compensated sensor in JEDEC standard SOIC-16
package with a single horizontal porting option.
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 analog output. This eliminates the need
for additional circuitry, such as a compensation network or
microcontroller containing a custom correction algorithm.
The SM6844 is shipped in sticks or tape & reel.
