MS580314BA01-00 TE Connectivity

MS5803-14BA Miniature 14 bar Module The MS5803-14BA is a new generation of high resolution pressure sensors with SPI and I2C bus interface. The MS5803- 14BA HE is the High Endurance version of MS5803-14BA sensor. It is optimized for depth measurement systems with a water depth resolution of 1cm and below. The sensor module includes a high linear pressure sensor and an ultra-low power 24 bit ADC with internal factory calibrated coefficients. It provides a precise digital 24 Bit pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. A high resolution temperature output allows the implementation of a depth measurement systems and thermometer function without any additional sensor. The MS5803- 14BA can be interfaced to any microcontroller. The FEATURES communication protocol is simple, without the need to High resolution module, 0.2mbar programming internal registers in the device. The gel protection Fast conversion down to 1 ms and antimagnetic stainless steel cap protects against 30 bar overpressure water resistant. This new sensor module generation Low power, 1 A (standby < 0.15 A) is based on leading MEMS technology and latest benefits from the Integrated digital pressure sensor (24 bit ADC) TE proven experience and know-how in high volume Supply voltage 1.8 to 3.6 V manufacturing of pressure modules have been widely used for Operating range: 0 to 14bar, -40 to +85 C over a decade. This sensing principle employed leads to very low hysteresis and high stability of both pressure and temperature I2C and SPI interface (Mode 0, 3) signal.
