MS5535B (RoHS^*)

PRESSURE SENSOR MODULE

• 0 - 14 bar absolute pressure range

• 6 coefficients for software compensation stored

on-chip

• Piezoresistive silicon micromachined sensor

• Integrated miniature pressure sensor 9 x 9 mm

• 15 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 MS5535B is a SMD-hybrid device including a piezoresistive pressure sensor and an ADC-Interface IC. 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. MS5535B 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.

Compared to the previous version (MS5535A) the temperature range has been improved (-40 to +125°C. Other

improvements concern the ESD sensitivity, current consumption and converter accuracy.

FEATURES

APPLICATIONS

• Supply voltage 2.2 V to 3.6 V

• Low supply current

• -40°C to +125°C operation temperature

• No external components required

• 15 Bit ADC resolution pressure measurement and

control systems

• Mobile water depth measurement systems

• Diving computers and divers watches
