Datasheet SDP8xx-Analog Differential Pressure Sensor with Analog Output ■ Configurable analog output ■ Calibrated and temperature compensated ■ Excellent repeatability, no drift Product Summary The SDP800 sensor family is Sensirion's series of differential pressure sensors designed for high-volume applications. The sensors measure the pressure of air and non-aggressive gases with superb accuracy and no offset drift. The sensors cover a pressure range of up to ±500 Pa (±2 inch H2O / ±5 mbar) and deliver outstanding accuracy, also at the lower end of the measuring range. The SDP800 features an analog ratiometric voltage output, which is configurable to linear or square root by a separate pin. The outstanding performance of these sensors is based on Sensirion's patented CMOSens® sensor technology, which combines the sensor element, signal processing, digital calibration and analog output on a small CMOS chip. The differential pressure is measured by a thermal sensor element using flow-through technology. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications. Benefits of Sensirion’s CMOSens® Technology ■ High reliability and long-term stability ■ Best signal to noise ratio ■ Industry-proven technology with a track record of more than 15 years ■ Designed for mass production ■ High process capability

1. Sensor Performance1.1 Differential Pressure Specification1 Parameter Unless otherwise noted, all sensor specifications are valid at 25°C with VDD = 3.3 V and absolute pressure = 966 mbar. For other pressure ranges contact Sensirion Output voltage integral non linearity and output voltage noise are not included. Note that the effect of output voltage integral non linearity and output voltage noise on accuracy is highly dependent on the output configuration (linear or square root). Includes repeatability Total accuracy/repeatability is a sum of zero-point and span accuracy/repeatability....

3. Pin Assignment The pin assignments of the SDP8xx-Analog can be found in Table 1. Pin no. Output curve selection input Ratiometric analog voltage output Table 1: SDP8xx-Analog pin assignment (bottom view) OCS: Output Curve Selection Input Config. Polarity Description Conversion to physical values AOut[V], VDD[V], Differential Pressure (DP) [Pa] Analog output is configured as a linear output. The sensor is not fully bidirectional in this configuration: -10% full500Pa scale to 100% full scale. Linear Analog output is a fully bi-directional output with square root conversion.

Figure 3: Footprint for PCB mounting (top view = sensor side). All dimensions in mm. A: Overall sensor dimensions B: Holes for additional mounting screws (optional) In case the sensor is not mounted on a PCB and is connected with a cable the SDP800 series cap is recommended. 5. Soldering Standard wave soldering systems may be used for soldering SDP800 series sensors. Reflow soldering is not feasible and may damage the sensor. The sensor ports must be protected from solder splash and flux during soldering. Figure 4 shows an appropriate temperature profile with maximum temperature values....
