Description: The MS5701 is a new generation of high resolution differential pressure sensors with SPI and I2C bus interface. It is optimized for water level measurement until ~50 cm. The sensor module includes a high linear pressure sensor and a 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 a thermometer function without any additional sensor. The MS5701-B can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need to programming internal registers in the device. This new sensor module generation is based on leading MEMS technology and latest benefits from Intersema’s proven experience and knowhow in high volume manufacturing of pressure sensors modules which have been widely used for over a decade. The sensing principle employed leads to very low hysteresis and high stability of both pressure and temperature signal.

Features:

• Low power, 1μA (standby <0.15μA)
• High stability, insensitive to mechanical stress
• Temperature range: -20°C to +85°C
