The MS5803-14BA is a new generation of high resolution
pressure sensors with SPI and I2C bus interface. 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 ΔΣ 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
communication protocol is simple, without the need to
programming internal registers in the device. The gel protection
and antimagnetic stainless steel cap protects against 30 bar
overpressure water resistant. This new sensor module generation
is based on leading MEMS technology and latest benefits from the
Intersema’s proven experience and know-how in high volume
manufacturing of pressure modules have been widely used for
over a decade. This sensing principle employed leads to very low
hysteresis and high stability of both pressure and temperature
signal.
