TDK InvenSense ICP-10125 Pressure and Temperature Sensor IC is based on MEMS capacitive technology which provides ultra-low noise at the lowest power. This enables the sensor IC to provide industry-leading relative accuracy, sensor throughput, and temperature stability. This 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 consumes only 1.3µA at 1Hz and is available in a small footprint 3.55 mm x 3.55 mm x 1.45 mm chimney package with waterproofing gel This gel provides IPx8 waterproofing up to 10ATM. This 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 smartwatches, altimeters, and barometers for portable device, home and building automation, and weather forecasting.
