1 INTRODUCTION
1.1 PURPOSE AND SCOPE
This document is a preliminary product specification, providing a description, specifications, and design related information for the
ICP-10111 Pressure Sensor.
Specifications are subject to change without notice. Final specifications will be updated based upon characterization of production
silicon.
1.2 PRODUCT OVERVIEW
The ICP-10111 is an ultra-low power, low noise, digital output barometric pressure and temperature sensor IC. It is based on an
innovative MEMS capacitive pressure sensor technology that can measure pressure differences with an accuracy of ±1 Pa at the
industry’s lowest power. The high accuracy MEMS capacitive pressure sensor is capable of measuring altitude differentials down to
8.5 cm without the penalty of increased power consumption or reduced sensor throughput.
The capacitive pressure sensor has a ±1 hPa absolute accuracy over its full range of 300 hPa -1100 hPa. The pressure sensor has an
embedded temperature sensor and 400 kHz I
2
C bus for communication. For power-critical applications, the ICP-10111 features a low
power mode of 1.3 µA at a noise of 3.2 Pa or for high performance applications, it features a low noise mode of 0.8 Pa while only
consuming 5.2 µA.
The ICP-10111 also offers industry leading temperature stability of the pressure sensor with a temperature coefficient offset of
±0.5 Pa/C. The high accuracy, temperature stability, and market leading low power consumption of 1.3 µA @1 Hz offered by ICP-
10111 makes it ideally suited for applications such as mobile phones, drone flight control and stabilization, indoor/outdoor
navigation (elevator, floor, and stair step detection), sports and fitness activity monitoring, and battery-powered IoT.
