SM5812

The Silicon Microstructures SM5812 and SM5852 series of OEM pressure sensors combines state-of-the-art pressure sensor technology with CMOS digital signal processing technology to produce an amplified, fully conditioned, multi-order pressure and temperature compensated sensor in a dual in-line package (DIP) configuration. Combining the pressure sensor with a custom signal conditioning ASIC in a single package simplifies the use of advanced silicon micromachined pressure sensors. Now, the pressure sensor can be mounted directly to a standard printed circuit board and an amplified, high level, calibrated pressure signal can be acquired from the digital interface or analog output. This eliminates the need of additional circuitry, such as a compensation network or microcontroller containing a custom correction algorithm.

The SM5812/SM5852 Series pressure sensors are based on SMI's highly stable, piezoresistive pressure sensor chips mounted on a ceramic substrate. An electronically programmable ASIC is contained in the same package to provide calibration and temperature compensation.

The model SM5812 is designed for operating pressure ranges from 0-5 PSI up to 0-100 PSI. The model SM5852 is designed for operating pressure ranges from 0-0.15 PSI up to 0-3 PSI. For both models, the sensor output is ratiometric with the supply voltage.
