The PWM output may be filtered to produce an analog voltage output.
The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of low-power, monolithic CMOS Sensor ICs with low drift and hysteresis, and excellent long term stability.
The humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory.
This ensures that the sensors are fully interchangeable, with no recalibration or software changes required.
The Si7007 is available in a 3x3 mm DFN package and is reflow solderable.
It can be used as a hardware- and software-compatible drop-in upgrade for existing RH/ temperature sensors in 3x3 mm DFN-6 packages, featuring precision sensing over a wider range and lower power consumption.
The optional factory-installed cover offers a low profile, convenient means of protecting the sensor during assembly (e.
g.
, reflow soldering) and throughout ...
