Product Attributes

Introduction

This product is an absolute pressure digital pressure sensor featuring high accuracy, low power consumption, and a wide operating temperature range, with integrated pressure and temperature measurement capabilities. The outputs from the pressure and temperature sensor elements are converted to 24-bit and 16-bit data respectively by an internal signal processing unit. Each unit is individually calibrated, with calibration coefficients stored in internal memory. In actual applications, these coefficients can be used to convert measurement results into true pressure and temperature values. Sensor measurement data and calibration coefficients are accessible via a serial I²C interface. The sensor is housed in a compact LGA8 package, making it easy to mount and integrate into systems.
