MEMS barometric pressure sensor offers ultra-low noise
Based on MEMS capacitive technology that offers lower power consumption and lower noise than competing pressure sensors technologies, the InvenSense ICP-20100 combines a barometric pressure and a temperature sensor in a small 2.0 x 2.0 x 0.8 mm package. The platform, says the company, improves on the industry-leading accuracy, long term drift, and temperature stability of its SmartPressure product family.
The device enables flexible user designs with multiple input voltage levels including 1.2V, 1.8V and 3.3V, and a choice of I²C, I3CSM and SPI interfaces. The ICP-20100 device can be configured to achieve ultra-low noise or ultra-low power performance and has the versatility to perform anywhere in between.
The ICP-20100 pressure sensor can operate over wide temperature ranges and deliver measurement accuracies required by a variety of applications including, 3D geolocation and emergency location service (E911), mobile indoor/outdoor navigation, sport and fitness activity tracking, and altitude-hold in drones. The sensor assists in extending battery life for always-on applications due to its extreme low-power consumption. With ultra-low noise pressure sensing capabilities, the ICP-20100 can detect altitude changes of less than 5 cm.
“With its low noise architectural innovations,” says Uday Mudoi, Director of Product Marketing at InvenSense, a TDK Group Company, “ICP-20100 underscores TDK’s continued commitment to bringing innovative human sensing solutions. ICP-20100 accurately measures pressure over a long period of time, enabling new critical and important applications such as determination of accurate location of E911 calls.”
A comprehensive development kit (DK-20100) and evaluation platform are also available along with necessary software to enable quick-to-market development of customer systems.
