MEMS barometric pressure sensor offers ultra low noise
Electronics company TDK Corporation has announced the worldwide availability of a new generation, feature-rich barometric pressure sensor, ideal for applications in smart phones, tablets, drones, and smart home appliances.

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.
