Silicon Microstructures’ SM933x series are high precision sensors for ultra-low air pressure measurements. These differential pressure sensors are constructed with state-of-the-art micro-electromechanical systems (MEMS) pressure transducer and CMOS mixed signal processing technologies. They combine a pressure sensor with signal-conditioning application-specific integrated circuit (ASIC) in a single package. These sensors are mounted directly on a circuit board and the high level calibrated pressure signal is accessible from the 16-bit I2C digital interface. Available in JEDEC standard SOIC-16 packages with a dual vertical porting option, they provide a pressure calibrated and temperature compensated output.
