SmartPressure™

MEMS Barometric Pressure Sensors

TDK InvenSense’s barometric pressure sensors use an innovative capacitive MEMS architecture to deliver lower power consumption and lower noise than competing technologies. The SmartPressure products can measure height change as small as 5 cm, which is less than the height of a single stair step.

With its industry-leading measurement accuracy and ultra-low power operation for always-on applications, the SmartPressure product family is best suited for smart phones, tablets, wearables, drones, and many other devices to determine accurate location of E911 calls, track changes in elevation for activity monitoring, support indoor or 3D navigation, and other motion- or position-based services.

The SmartPressure product family includes support for waterproofing to 10 ATM. 

Each has a Development Kit so that you can rapidly evaluate these within your application.

ICP‑20100

Achieves industry-leading relative accuracy, sensor throughput, temperature stability, and industry’s lowest pressure noise of 0.4 Pa RMS while attaining the industry’s lowest power consumption of 1.0 µA.

Provides lower power: no current consumption during capacitance measurement. Also provides lower noise: thermal noise of piezo resistors (competition) fundamentally limits sensitivity and resolution.

Package: 2 × 2 × 0.8mm 10 leads LGA.

ICP‑10125

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 8.5 cm, less than the height of a single stair step.

Package: 3.55 × 3.55 × 1.45 mm chimney package with waterproofing gel providing IPx8 waterproofing to 10 ATM.

ICP‑10101

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.

Package: 2 × 2 × 0.72 mm 10 leads LGA.

ICP‑10111

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.

Package: 2 × 2.5 × 0.92 mm 8 leads LGA.
