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

OVERVIEW

The ICP-10111 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 × 2.5 × 0.92 mm 8‑pin LGA package, the ICP‑10111 is ideally suited for mobile phones, wearable fitness monitoring, drones, and battery powered IoT.

The ICP-10111 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.

NextNav announced that the ICP-10111, is the first to achieve NextNav Certified status. The performance data produced by the NextNav Certified process provides independently verified data on sensor accuracy and gives hardware manufacturers guidelines for optimal integrations.

Over a six-week period, the ICP-10111 was subjected to a rigorous testing regimen jointly designed by InvenSense and NextNav engineers. Using real-world data sets from NextNav’s nationwide network of altitude stations, sensor components were tested against a variety of operational scenarios.
