Digital Pressure Sensors MS5535 For Depth & Watch Applications

DESCRIPTION

The MS5535 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. MS5535 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.  The temperature range is -40°C to +125°C.

There is a new high pressure version (0-30 bar) version of the MS5535 called the MS5535C-60.
