High Performance Feature‑Rich, Low Noise, Low Power SmartPressure™ Sensor

OVERVIEW

The ICP-20100 is a barometric pressure sensor based on MEMS capacitive technology, improving our lead in the development of ultra-low noise at the lowest power and progressing our industry-leading relative accuracy, sensor throughput, and temperature stability. The ICP‑20100 achieves the industry’s lowest pressure noise of 0.4 Pa RMS, while attaining the industry’s lowest power consumption of 1.0 µA, and retains excellent temperature stability with a temperature coefficient of ±0.5 Pa/°C.

The ICP-20100 capacitive pressure sensor can operate over wide temperature ranges and a variety of applications, meeting US carrier requirements for 3D geolocation and emergency applications such as the enhanced 911 (E911) system, enabling mobile indoor/outdoor navigation, improved activity identification for leisure, sport and fitness purposes, and altitude‑hold in drones. The sensor assists in extending battery life for “AlwaysOn” applications due to its extreme low-power consumption.
