TE Connectivity / Measurement Specialties MS5525DSO Pressure Sensors

TE Connectivity's (TE) Measurement Specialties MS5525DSO pressure sensors are a new generation of digital small outline sensors with SPI and I2C bus interfaces. These sensor modules include a pressure sensor and an ultra-low-power 24-bit sigma-delta analog to digital converter (ΔΣ ADC) with internal factory-calibrated coefficients. MS55525DSO provides a 24-bit digital pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. This TE sensor can be interfaced with virtually any microcontroller. The communication protocol is simple and does not require programming internal registers in the device. MS5525DSO offers dual- or single-port configurations and can measure absolute, gauge, compound, and differential pressure from 1psi to 30psi.
