Using the latest in MEMS technology, the MS5701 has a low supply voltage of 1.8 to 3.6 V with 1 mA power consumption. Furthermore, the MS5701 pressure sensor has a high resolution of 0.0004 in. of water (0.001 mbar) and a fast conversion of 0.54 milliseconds. A 24-bit pressure and temperature output allows for integration to any microcontroller. The I2C or SPI interface communicates up to 20 MHz.
With an operating temperature range of -20 to 85°C, the MS5701 offers excellent accuracies. For example, a model calibrated for 5 in. of water (differential) has an accuracy of ±0.04 in. at 25°C and ±0.1 in. over the entire operating temperature range. Low hysteresis and high stability of the pressure and temperature signal make the MS5701 reliable in demanding, high performing applications. Typical uses for the MS5701 include respirators, ventilators, CPAP and sleep apnea, and more.
