SI7055-A20-IMR General Description

DescriptionThe Si7005 is a digital relative humidity and temperature sensor. This monolithic CMOS IC integrates temperature and humidity sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C host interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables the construction of a low-power, monolithic CMOS sensor IC with low drift and hysteresis and excellent long term stability.Features■ Relative Humidity Sensor •± 4.5% RH (maximum @ 0–80% RH)■ Temperature Sensor •±0.5 ºC accuracy (typical) •±1 ºC accuracy (maximum @ 0 to 70 °C)■ 0 to 100% RH operating range■ –40 to +85 °C (GM) or 0 to +70 °C operating range (FM)■ Wide operating voltage range (2.1 to 3.6 V)■ Low Power Consumption •240 µA during RH conversion■ I2C host interface■ Integrated on-chip heater■ 4x4 mm QFN package■ Excellent long term stability■ Factory calibrated■ Optional factory-installed cover •Low-profile •Protection during reflow •Excludes liquids and particulates (hydrophobic/oleophobic)Applications■ Industrial HVAC/R■ Thermostats/humidistats■ Respiratory therapy■ White goods■ Micro-environments/data centers■ Automotive climate control and de-fogging■ Asset and goods tracking
