ICP-10111

Pressure Sensors Transducers Overview

The ICP-10111 is a high-precision, low-power barometric pressure and temperature sensor manufactured by TDK InvenSense. It features an absolute pressure measurement range of 30kPa to 110kPa (4.35PSI ~ 15.95PSI) with a resolution of ±1 Pa, equivalent to an altitude change of 8.5 cm. The device provides temperature accuracy of ±0.4°C within a working temperature range of -40°C to +85°C. It operates on a supply voltage of 1.8V and offers digital output via I²C interface. The component is housed in a compact 8-VFLGA package measuring 2x2.5 mm.

Pressure Sensors Transducers Procurement Notes

Verify the specific ordering suffix required for your packaging preference, such as tape-and-reel or cut-tape options. Confirm that the current revision matches your design requirements, as the manufacturer has issued end-of-life notifications for this product line. Ensure compatibility with existing firmware libraries before procurement, given the component's discontinued status.

Pressure Sensors Transducers Selection Notes

Select this component when high vertical resolution is critical for altitude estimation. The integrated temperature sensor simplifies calibration requirements compared to separate solutions. Consider the small footprint for space-constrained designs. Evaluate power consumption profiles against application duty cycles to ensure battery life targets are met.

Pressure Sensors Transducers Part Context

The ICP-10111 belongs to the SmartMotion series of MEMS sensors from TDK InvenSense. It is part of the ICP-101xx family, which includes variants like the ICP-10100 and ICP-10125. These sensors are designed for consumer and industrial applications requiring accurate environmental sensing. The series emphasizes the balance between precision and power efficiency.

Pressure Sensors Transducers Replacement Considerations

Public documentation indicates the ICP-101xx series has reached end-of-life. No direct substitute part numbers are confirmed in official sources. Designers should evaluate alternative high-accuracy barometric sensors from other manufacturers or consider redesigning for available inventory.
