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
