OverviewThe S123 SIP(System-in-a-Package) solution comprises of a resistive bridge type pressure sensor and a 24-bit ADCfor high resolution and accurate pressure measurements. The fully calibrated pressure and temperature compensated digital output makes the S123 solution simple to use.The ADC comprise of an internalcalibration logic that provides accuratepressure and temperature measurements to the applicationvia the SPI or I²C interface. There is no need to separately download internal calibration coefficients and have the host micro-controller conduct complicated compensation calculations.ApplicationsAltimetersPortable and Stationary BarometersWeather StationsGPS ApplicationsHard Disk Drives(HDD)Industrial EquipmentAir Control SystemsVacuum SystemsBenefitsLow Power Consumption.
