TDK InvenSense ICP-10125 Pressure & Temperature Sensor IC

TDK InvenSense ICP-10125 Pressure and Temperature Sensor IC is based on MEMS capacitive technology that provides ultra-low noise at low power. This enables the sensor IC to provide industry-leading relative accuracy, sensor throughput, and temperature stability. The ICP-10125 sensor IC can measure pressure differences with an accuracy of ±1Pa. This accuracy enables altitude measurement differentials as small as 8.5cm. The ICP-10125 IC consumes only 1.3µA at 1Hz and is available in a small footprint 3.55mm x 3.55mm x 1.45mm chimney package with waterproofing gel. This gel provides IPx8 waterproofing up to 10ATM. The sensor IC offers an industry-leading temperature coefficient offset of ±0.5Pa/°C and operates within -40°C to 85°C temperature range. Applications include smart watches, altimeters and barometers for a portable device, home and building automation, and weather forecasting.
