SM9235-BCE-S-300-000

SM9235-BCE-S-300-000 is a digital, ultra-low pressure sensor in a SOIC-16 dual vertical package. 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. Typical applications include CPAP / sleep apnea, ventilator, gas flow instrumentation, air flow measurement, HVAC / VAV, pressure transmitter, pressure switches, pneumatic gauges and safety cabinets.
