AVAILABLE OPTIONS
Gel Coat (-F Option)
The MS4525DO is designed for non-ionic and clean dry air applications. Select this option for added protection in
high humidity or slightly corrosive environments with the application of a silicone gel elastomer to sensor and
ASIC. For questions concerning media compatibility, contact the factory.
Low Power (-L Option)
Select this option for battery powered or handheld device applications. In this configuration, the sensor and
calibration microcontroller are powered down, drawing a current of ~ 0.6uA (Vs=5.0 Vdc). When the master
sends a Read MR (measurement request) command (I
2
C or SPI); the sensor is “awaken” and begins the
measurement cycle; data is then placed onto the output registers. The sensor and calibration microcontroller are
powered down again, awaiting the Read DF (data fetch) command from the master.
