TDK InvenSense ICP-20100

The ICP- 20100 pressure sensor provides a high- accuracy, low power, barometric pressure and temperature sensor solution, that integrates a capacitive pressure sensor for monitoring pressure changes in the range of 30 to 110kPa. The ICP- 20100 integrates a DSP module for on- chip calibration with an Analog- to- Digital converter (ADC), digital filtering, a FIFO and has I²C, 13C^SM and SPI interfaces available. The solution can be configured to achieve ultra- low noise or ultra- low power performance and is flexible to perform anywhere in- between. Additionally, the filters can be enabled to allow even lower noise performance or activate features such as filtering of pressure glitches (e.g. opening/closing a window). The ICP- 20100 is available in a closed package with a vent hole.
