6. OPERATING CHARACTERISTICS TABLE
All parameters are specified at Vdd = 3.3 V or 5 V DC supply voltage (as per P/N counter in table 10) at 25oC, unless otherwise noted. No. Characteristic Symbol Minimum Typical Maximum Units Supply Current at 3.3V (e) I 1 VDD3p3 3.3 4.1 mA Supply Current at 5.0V (e) IVDD5p0 3.9 5.0 2 Digital Pressure Output @ PMIN OUTMIN -26,215 Counts 3 Digital Pressure Output @ PMAX OUTMAX +26,214 Counts 4 Digital Full Scale Span FS 52,429 Counts 5 Resolution (Digital Output) 16 Bits 6 Update Rate 2000 Hz SM9233 – 250 Gauge -1.25 ± 0.25 1.25 %FS Digital AZ 7 Output SM9235 – 300 Gauge ACC -1.0 ± 0.2 1.0 %FS AZ Accuracy (f, g, h) SM9236 – 600 Gauge -1.0 ± 0.1 1.0 %FS SM9233 – 250 Gauge -2.75 ± 0.5 2.75 %FS Digital Output 8 SM9235 – 300 Gauge ACC -2.3 ± 0.4 2.3 Accuracy (f) SM9236 – 600 Gauge -1.25 ± 0.3 1.25 %FS 9 Bandwidth BW 20 Hz 10 Position Sensitivity SG 0.1 %FS/g from supply VDD > 3.0 V Power-up 11 to output settled to 90% t 5 ms time* UP of final value pressure step response; Step response 12 output rising from 10% to t ms time* RESP 1 90% of final value pressure step response; Step response 13 output settling to full t 10 ms settling time* SETTLE accuracy * Not tested in production
Notes:
e. Supply current given for continuous operation. Device can be set to sleep mode with significantly lower power consumption. Refer to section 11 for details. f. The accuracy specification applies over all operating conditions in dry clean air. This specification includes the combination of linearity, repeatability, and hysteresis errors over pressure, temperature, and 3.3 V supply voltage. g. Based on system level autozero at 25 oC after board mount or solder reflow. h. Based on sample testing during initial product qualification, not tested in production.
