TDK Corporation (TSE: 6762) announced worldwide availability of the InvenSense ICP-10125, part of the SmartPressureTM family of the MEMS barometric pressure sensor platform. The ICP-10125 achieves the industry’s lowest pressure noise of 0.4 Pa RMS, attains the industry’s lowest power consumption of 1.3 µA, and ensures excellent temperature stability with a temperature coefficient of ±0.5 Pa/°C.
The ICP-10125 device combines a barometric pressure and a temperature sensor in a small 3.55 mm x 3.55 mm x 1.45 mm chimney package with waterproofing gel, providing IPX8 waterproofing to 10 ATM. The uniform machined lid and chimney with groove enable easier handling at production and assembly of customer products.
The solution is aimed at the fitness, smart watch, and portable device markets that assist in fitness activity monitoring, location tracking for E911 calls, and indoor/outdoor navigation (dead-reckoning, floor/elevator/step detection).
The InvenSense SmartPressureTM family uses an innovative capacitive MEMS architecture to deliver lower power consumption and lower noise than competing pressure sensors technologies. With its ultra-low noise and low power consumption, ICP-10125 is ideally suited for wearable fitness monitoring and battery powered IoT. It can measure height change as small as 8.5 cm, less than the height of a single stair step.
“ICP-10125 delivers high accuracy, low power, temperature stability, and waterproofing in a small package footprint targeting the wearable market,” said Uday Mudoi, Director of Product Marketing at InvenSense, a TDK group company. “It enables determination of accurate location of E911 calls, tracks changes in elevation for activity monitoring, and extends battery life of always-on motion sensing applications.”
InvenSense ICP-10125 is currently available for worldwide distribution. A comprehensive development kit (DK-10125) and evaluation platform are also available along with necessary software to enable quick-to-market development of customer systems. In addition to the ICP-10125, the ICP-10101 and ICP-10111 pressure sensor products are already available in worldwide distribution.
