LPS25HTR

Pressure Sensors Transducers Overview

The LPS25HTR is a digital output barometric pressure sensor from STMicroelectronics, featuring a piezoresistive sensing element. It operates within an absolute pressure range of 260 hPa to 1260 hPa (26 kPa to 126 kPa). The device provides high resolution with a 24-bit output and maintains an accuracy of 100 Pa. It supports I2C and SPI interfaces for data communication. Powered by a supply voltage between 1.7 V and 3.6 V, it draws a typical operating current of 4 µA. The sensor is housed in a compact 10-LLGA package (2.5x2.5 mm) and functions reliably across a temperature range of -30°C to +105°C.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the component meets RoHS standards if required for your region. Ensure the selected distributor sources directly from STMicroelectronics or authorized channels to guarantee authenticity. Check for moisture sensitivity handling requirements during storage and assembly. Validate that the 10-LLGA footprint matches your PCB design constraints before finalizing procurement.

Pressure Sensors Transducers Selection Notes

Select this model when a low-power, high-accuracy barometer is needed for portable devices. The integrated temperature compensation simplifies system calibration compared to non-compensated sensors. Consider the 24-bit resolution for applications requiring precise altitude changes. The dual interface options allow flexibility in microcontroller selection. Evaluate the small package size against available board space constraints.

Pressure Sensors Transducers Part Context
