MS5535-30C (RoHS^*) PRESSURE SENSOR MODULE
• 0 - 30 bar absolute pressure range
• 6 coefficients for software compensation stored
on-chip
• Piezoresistive silicon micromachined sensor
• Integrated miniature pressure sensor 9 x 9 mm
• 16 Bit ADC
• 3-wire serial interface
• 1 system clock line (32.768 kHz)
• Low voltage and low power consumption

DESCRIPTION
The MS5535-30C is a high-pressure version of MS5535C pressure sensor module. It contains a precision
piezoresistive pressure sensor and an ADC-Interface IC. It uses an antimagnetic polished stainless ring for
sealing O-ring. It provides a 16 Bit data word from a pressure and temperature dependent voltage. Additionally
the module contains 6 readable coefficients for a highly accurate software calibration of the sensor. MS5535-
30C is a low power, low voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is
used for all communications with a microcontroller.
FEATURES
• Resolution 3.0 mbar
• Supply voltage 2.2 V to 3.6 V
• Low supply current < 5uA
• Standby current < 0.1 uA
• -40°C to +125°C operation temperature
• 16 Bit ADC resolution pressure measurement
and control systems
APPLICATIONS
• Mobile water depth measurement systems
• Diving computers and divers watches
