SI7022-A20 Datasheet HUMIDITY/TEMPERATURE SENSOR

Manufacturer: Silicon Laboratories

General Description

The Si7022 Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and a PWM output.

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.
