The SOIC pressure sensors in the SM4X91 series are analog/digital OEM sensors with a new silicon sensing element and modern electronic signal conditioning unit. The integrated digital signal processor permits calibration and temperature compensation during production.
The fully calibrated SM4291/SM4391/SM4491 sensors are supplied in a standard SOIC16 package with two vertical pressure connectors for SMD assembly. Pressure-proportional information in I2C format or as an analog 0.6–5.4-V voltage signal acts as an output signal. SM4291/SM4391/SM4491 are autonomous sensors which do not require any additional circuitry. These are suitable for reflow soldering and automatic assembly on a PCB.
The sensor is available in a relative SM4291 or differential SM4391 sensor version or as asymmetrical, bidirectional, differential pressure sensor SM4491.
