ICP-10101

High-Accuracy, Low-Power, 10 atm Waterproof Barometric Pressure & Temperature Sensor IC

The ICP-10101 barometric 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 ±1 Pa, an accuracy enabling altitude measurement differentials as small as 5 cm, less than the height of a single stair step.

Consuming only 1.3 µA @1 Hz, available in a small footprint 2 × 2 × 0.72 mm 10‑pin LGA package, the ICP‑10101 is ideally suited for mobile phones, wearable fitness monitoring, drones, and battery powered IoT.

The ICP-10101 offers an industry leading temperature coefficient offset of ±0.5 Pa/°C. The combination of high accuracy, low power, and temperature stability in a small footprint enables higher performance barometric pressure sensing for sports activity identification, mobile indoor/outdoor navigation, and altitude‑hold in drones.
