Block diagram MS5540C |
DESCRIPTION
The MS5540C 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 MS5540C
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 6.2x6.4qmm
Pressure range: 10...1100mbar (0.15 ... 16 PSI) abs.; operating
temperature: -40 ... +85°C
The MS5540-C is fully software compatible to previous version MS5540-B.
*Modules are pressure sensors, whose output
signals have to be calculated by an external microprocessor
