Description
The MS5541C is the miniature version of MS5535C pressure sensor module. It contains a precision piezoresistive pressure sensor and an improved version of the 16 Bit Micropower Sensor interface IC known from the MS5535C. Compared to the previous version the ESD sensitivity has been improved to 4 kV on all pins. In addition to this the MS5541C is from its outer dimensions compatible to the MS54xx series of pressure sensors. It uses an antimagnetic polished stainless steel ring for sealing with O-ring. The sensor provides 16 Bit pressure and temperature data via a 3 wire serial interface that can be easily interfaced with 4 Bit low power microcontrollers. 64 Bit of factory programmed PROM provides calibration data for a highly accurate pressure and temperature calculation. The MS5541C is fully software compatible to the MS5535C and previous versions of MS5541.
