Measurement Specialties offers digital barometric sensor in a compact QFN package

摘要

The MS5637 digital barometric pressure sensor uses an integrated 24-bit ADC to precisely process pressure and temperature values in as little as 0.5 msec. A low power draw of 0.6 uA combined with a compact footprint of 3×3×0.9 mm makes this high-resolution module ideal for handheld, mobile devices. The MS5637's high-resolution temperature output enables operation as an altimeter or thermometer, and a high-linearity pressure sensor provides an altitude resolution of 13 cm at sea level for accurate measurements. Standby power is less than 0.15 uA at 25℃, supply-voltage ranges from 1.5 to 3.6V, and the ADC interfaces with microcontrollers via an PC interface. The sensor operates from 300 to 1200 mbar over an extended temperature range of -40 to +85℃, with a long-term stability of ±1 mbar per year.
