ICP-20100 Pressure and Temperature Sensor IC
ICP-20100
High Accuracy, Low Power, Barometric Pressure and Temperature Sensor IC
General Information
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 110 kPa. 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, I3CSM, 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.
Features
