The SM9333/9336 are digital, ultra-low pressure sensors offering state-of-the-art MEMS pressure transducer technology and CMOS mixed signal processing to produce a digital, fully-conditioned, multi-order pressure and temperature-compensated sensor in JEDEC standard SOIC-16 package with a dual vertical porting option. It is available as a differential pressure sensor.
The total accuracy after board mount and system level auto-zero is less than 1%FS. The excellent warmup behavior and long term stability further assures its expected performance over the life of the part. The SM9333/SM9336 are shipped in sticks or tape & reel.
