The SOIC pressure sensors in the SM4X21 series are 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 SM4221, SM4321 and SM4421 sensors are supplied in a standard SOIC16 package with two vertical or horizontal pressure connectors for SMD assembly. Pressure-proportional information in I2C format acts as an output signal. SM4221/SM4321/SM4421 are autonomous sensors which do not require any additional circuitry.
SM4221/SM4321/SM4421 are suitable for reflow soldering and automatic assembly on a PCB.
The sensor is available in a relative SM4221 or differential SM4321 sensor version or as asymmetrical, bidirectional, differential pressure sensor SM4421.
