TDK Invensense ICP-10125 10atm pressure and temperature sensor IC
TDK Invensense announces ICP-10125 10atm waterproof barometric pressure and temperature sensor IC

The ICP-10125 pressure sensor is based on MEMS capacitive technology which provides ultra-low noise at the lowest power, enabling industry-leading relative accuracy, sensor throughput, and temperature stability. The pressure sensor can measure pressure differences with an accuracy of ±1Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm, less than the height of a single stair step.
Consuming only 1.3μA @1Hz, the device is available in a small footprint 3.55mm × 3.55mm × 1.45mm chimney package with waterproofing gel providing IPx8 waterproofing to 10 ATM. The ICP-10125 is ideally suited for wearable fitness monitoring and battery powered IoT.
The ICP-10125 offers an industry leading temperature coefficient offset of ±0.5Pa/ºC. The combination of high accuracy, low power, temperature stability, waterproofing in a small footprint enables higher performance barometric pressure sensing for sports activity identification and mobile indoor/outdoor navigation.
