DK-10101 [TDK]

The ICP-101xx 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 I2C bus for communication. For power-critical applications, the ICP-101xx 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-10100 and ICP-10110 has three 0.025 mm package openings, making waterproof to 1.5m for 30 minutes. The ICP-101xx also offers industry leading temperature stability of the pressure sensor with a temperature coefficient offset of ±0.5 Pa/°C.
