NXP MPL115A2

绝对I²C2.375V ~ 5.5V

Overview

The MPL115A2 is a miniature I2C digital barometer in 8 pin LGA package. This absolute pressure sensor is suitable for low cost applications. Low current consumptions of 5µA during active mode and 1µA during shutdown (sleep) mode are essential when focusing on low power applications. The MPL115A2 employs MEMS pressure sensor with conditioning IC to provide accurate pressure measurements. An integrated ADC converts pressure and temperature sensor readings to digitized outputs via I2C port. Factory calibration data is stored internally in an on-board ROM. Utilizing raw sensor output and calibration data, the host microcontroller executes compensation algorithm to render compensated absolute pressure with ±1kPa accuracy. The MPL115A2 pressure sensor's small form factor, low power capability, precision and digital output optimize it for barometric measurement applications.
