SM9233 / SM9235 / SM9236
The SOIC pressure sensors in the SM923X series are digital OEM sensors for the low pressure range with a new silicon sensing element and modern electronic signal conditioning unit. The integrated ASIC permits calibration and temperature compensation during production.
The fully calibrated SM9233, SM9235 and SM9236 sensors are supplied in a standard SOIC16 package with two vertical pressure connectors for SMD assembly. angeboten. Pressure-proportional information and temperature in I2C format act as an output signal. The SOIC pressure sensors are autonomous and do not require any additional circuitry.
The SM923X sensors are compensated for and calibrated across the entire operating temperature range of -20 to +85°C and suitable for reflow soldering and automatic assembly on a PCB.
The differential low-pressure sensor is available for three different pressure ranges of 250 Pa, 300 Pa and 600 Pa and is also suitable for relative pressure sensing.
Variants of the SM9233 / SM9233 / SM9236
SM9233 pressure ranges differential: 0 – 2.5 mbar
SM9235 pressure ranges differential: 0 – 3.0 mbar
SM9236 pressure ranges differential: 0 – 6.0 mbar

The SOIC sensors in the SM923X series are supplied by AMSYS as standard products with a 3.3-V supply. An optional 5-V version is also available. The accuracy of these ultralow pressure sensors can be further increased by an offset correction function (AutoZero) which is recommended by the manufacturer. On request the pressure range can also be adapted to suit specific customer requirements.
