MS5849-07BA36

The MS5849 is a new generation of high-resolution pressure sensors from TE Connectivity with SPI / I2C bus interface. The pressure sensor includes a high linearity pressure sensor and an ultra-low power 24-bit ΔΣ ADC with internal factory alibrated coefficients. It provides precise digital 24-bit pressure and temperature values and different operation modes that allow the user to optimize for conversion speed and current consumption. The MS5849 can be interfaced to virtually any microcontroller. Its small dimensions of 3.3 mm x 3.3 mm x 2.7 mm and its low power consumption allow easy integration in user applications. This new sensor generation is based on leading MEMS technology and latest benefits from TE proven experience and know-how in high volume manufacturing of pressure sensors, which have been widely used for over three decades.
