SI7006-A20-IM1R Description

 Factory-calibrated I2C Interface Integrated on-chip heater 3x3 mm DFN Package Excellent long term stability Optional factory-installed coverLow-profileProtection during reflowExcludes liquids and particulates Micro-environments/data centers Automotive climate control anddefogging Asset and goods tracking Mobile phones and tabletsThe Si7006 I2C Humidity and Temperature Sensor is a monolithic CMOS ICintegrating humidity and temperature sensor elements, an analog-to-digitalconverter, signal processing, calibration data, and an I2C Interface. The patenteduse of industry-standard, low-K polymeric dielectrics for sensing humidity enablesthe construction of low-power, monolithic CMOS Sensor ICs with low drift andhysteresis, and excellent long term stability.The humidity and temperature sensors are factory-calibrated and the calibrationdata is stored in the on-chip non-volatile memory. This ensures that the sensorsare fully interchangeable, with no recalibration or software changes required.The Si7006 is available in a 3x3 mm DFN package and is reflow solderable. It canbe used as a hardware- and software-compatible drop-in upgrade for existing RH/temperature sensors in 3x3 mm DFN-6 packages, featuring precision sensingover a wider range and lower power consumption. The optional factory-installedcover offers a low profile, convenient means of protecting the sensor duringassembly (e.g., reflow soldering) and throughout the life of the product, excludingliquids (hydrophobic/oleophobic) and particulates.The Si7006 offers an accurate, low-power, factory-calibrated digital solution idealfor measuring humidity, dew-point, and temperature, in applications ranging fromHVAC/R and asset tracking to industrial and consumer platforms.Ordering Information:See page 28.Pin AssignmentsTop ViewSDAGNDDNC123654SCLVDDDNCPatent Protected.
