LPS331APTR Description

Short technical summary and product information.

The LPS331APTR from STMicroelectronics is an ultra-compact absolute piezoresistive pressure sensor designed for a variety of applications. It offers a pressure range of 260 to 1260 mbar with a high-resolution mode of 0.020 mbar RMS. The sensor operates with low power consumption, drawing 5.5 µA in low-resolution mode and 30 µA in high-resolution mode.

 

Key features include embedded temperature compensation, a 24-bit ADC, and selectable output data rates from 1 Hz to 25 Hz. It supports both SPI and I2C interfaces and operates over a supply voltage range of 1.71 V to 3.6 V. The sensor boasts high shock survivability of 10,000 g and is guaranteed to operate within a temperature range of -40 °C to +85 °C.

 

The LPS331APTR is housed in a small, thin 16-HCLGA package, suitable for surface mounting. The package is designed with a hole to allow external pressure to reach the sensing element. This sensor is ideal for applications such as altimeters and barometers for portable devices, indoor and outdoor navigation, and weather station equipment.
