MS580314BA01-00

MS580314BA01-00 is a miniature variometer module. It is optimized for altimeters and variometers with an altitude resolution of 10cm. The sensor module includes a high linearity pressure sensor and an ultra-low power 24-bit ΔΣ ADC with internal factory-calibrated coefficients. It provides a precise digital 24-bit pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. A high-resolution temperature output allows the implementation of an altimeter/thermometer function without any additional sensor. The communication protocol is simple, without the need to program internal registers in the device. It is used in applications such as mobile altimeter/barometer systems, bike computers, adventure or multi-mode watches, variometers, and dataloggers.
