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.
