DESCRIPTION
The SM923x series are digital, ultra-low pressure sensors offering Combining the pressure sensor with a signal-conditioning ASIC in a state-of-the-art MEMS pressure transducer technology and CMOS single package simplifies the use of advanced silicon micro-machined mixed signal processing technology to produce a digital, fully pressure sensors. The pressure sensor can be mounted directly on a conditioned, multi-order pressure and temperature compensated standard printed circuit board and a high level, calibrated pressure sensor in JEDEC standard SOIC-16 package with a dual vertical signal can be acquired from the digital interface. This eliminates the porting option. It is available in a gauge pressure configuration. need for additional circuitry, such as a compensation network or microcontroller containing a custom correction algorithm. The total accuracy after board mount and system level autozero is less than 1%FS. The excellent warmup behavior and long term The SM9233/SM9235/SM9236 are shipped in sticks or tape & reel. stability further assures its expected performance over the life of the part.
