MS5541C (RoHS^*)

MINIATURE 14 bar MODULE

• 0 - 14 bar absolute pressure range

• 6 coefficients for a software compensation stored

on-chip

• Piezoresistive silicon micromachined sensor

• Integrated pressure sensor 6.2x6.4 mm

• 16 Bit ADC

• 3-wire serial interface

• 1 system clock line (32.768 kHz)

• Low voltage and low power consumption

• RoHS-compatible & Pb-free*

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 4kV 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.
