MS5803-07BA Altimeter and diving pressure sensor The MS5803-07BA is a new digital, fully compensated pressure 2 sensor with SPI and I C bus interface. The MS5803-07BA HE is the high endurance pad technology version of the MS5803-07BA pressure sensor module. It is optimized for altimeter and in the same time water depth measurement with high resolution and accuracy. The sensor module includes a high linearity 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 FEATURES the user to optimize for conversion speed and current consumption. A high resolution temperature output allows the Excellent accuracy for both altimeter and diving implementation of a thermometer function without any additional applications until 60m depth sensor. The MS5803-07BA can be interfaced to virtually any Operating range: 0 to 7bar, -20 to +85 C microcontroller. The communication protocol is simple, without the High resolution module: 0,4m air / 1mm water need of programming internal registers in the device. The gel Fast conversion down to 1 ms protection and antimagnetic stainless steel cap allows the use in 100m waterproof watches. This new sensor module generation is Low power, 1 A (standby < 0.15 A) based on leading MEMS technology and latest benefits from TE Integrated digital pressure sensor (24 bit ADC) proven experience and know-how in high volume manufacturing Supply voltage 2.2 to 3.6 V which have been widely used for over a decade. I2C and SPI interface (Mode 0, 3) No external components (Internal oscillator) Excellent long term stability Hermetically sealable for outdoor devices High Endurance (HE version) APPLICATIONS Dual mobile altimeter / depth meter systems Adventure or multi-mode watches Diving computer SENSOR SOLUTIONS ///MS5803-07BA 08/2017 Page 1 MS5803-07BA Altimeter and diving pressure sensor TECHNICAL DATA Sensor Performances (VDD = 3 V) Pressure Min Typ Max Unit Range 0 7 bar ADC 24 bit Resolution (1), Altimeter 0.04 mbar mode Accuracy 0C to +60C, -4.5 +4.5 mbar 400 to 1100 mbar (2) Accuracy 0C to + 40C, -50 +50 mbar 400 to 7000 mbar 0.5 / 1.1 / 2.1 / Response time (2) ms 4.1 / 8.22 Long term stability 1 mbar/yr Temperature Min Typ Max Unit Range -20 +85 C Resolution <0.01 C Accuracy -3 +3 C Notes: (1) Oversampling Ratio: 4096 (2) With auto-zero at one pressure point (3) Oversampling Ratio 4096 / 2048 / 1024 / 512 / 256 FUNCTIONAL BLOCK DIAGRAM VDD PS Meas.
