MS5803-01BA
Miniature Variometer Module
? High resolution module, 10cm
? Fast conversion down to 1 ms
? Low power, 1 μA (standby < 0.15 μA)
? Integrated digital pressure sensor (24 bit ?Σ ADC)
? Supply voltage 1.8 to 3.6 V
? Operating range: 10 to 1300 mbar, -40 to +85 °C
? I2C and SPI interface up to 20 MHz
? No external components (Internal oscillator)
? Excellent long term stability
? Hermetically sealable for outdoor devices
DESCRIPTION
The MS5803-01BA is a new generation of high resolution altimeter sensors from Measurement Specialties with
SPI and I2C bus interface. It is optimized for altimeters and variometers with an altitude resolution of 10 cm. The
sensor module includes a high linearity pressure sensor and an ultra low power 24 bit ?Σ 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 an altimeter/thermometer function without any
additional sensor. The MS5803-01BA can be interfaced to virtually any microcontroller. The communication
protocol is simple, without the need of programming internal registers in the device. The gel protection and
antimagnetic stainless steel cap allows the use in 100m waterproof altimeter/compass watches. This new
sensor module generation is based on leading MEMS technology and latest benefits from MEAS proven
experience and know-how in high volume manufacturing of altimeter modules, which have been widely used for
over a decade. The sensing principle employed leads to very low hysteresis and high stability of both pressure
and temperature signal.
