The MS5540 pressure measurement miniature module
consists of a SMD-hybrid device including a piezoresistive
pressure cell and an ADC-Interface IC. It provides 16 Bit
data words from a pressure- and temperature-dependent voltage.
Additionally the module contains 6 readable coefficients for
a highly accurate software calibration for the pressure and
temperature measurement. The MS5540 is a
low-power, low-voltage device with automatic power down (ON/OFF)
switching. A 3-wire interface is used to communicate
with a microcontroller.
The devices have a very low standby-current. The optimal compromise
about refresh rate and average current consumption can
individually be defined by the application software.
MS5540-CM: protected by a metal ring filled with silicon gel on a ceramic hybrid 6.2x6.4mm
Pressure range: 0.15 ... 16 PSI abs.; operating temperature: -40 ... +85°C
The MS5540-C is fully software compatible to previous version MS5540-B.
