Sensor pressao 30 a 120kPa e temperatura - RCPS120
The RCPS120 is a capacitive absolute pressure sensor solution with a fully calibrated pressure and temperature compensated digital output for low pressure
applications, such as barometric sensing. Low current consumption (<1µA @ 25°C in Sleep Mode) and operating supply voltage range 2.3V to 5.5V targets battery
and other low-power applications.
The RCPS120 SiP (System-in-a-Package) solution comprises of an ultra-small capacitive MEMS pressure sensor and a conditioning ASIC for accurate pressure measurements. An integrated sigma-delta based ADC combined with internal calibration logic provides accurate pressure and temperature measurements to the
application via the SPI or I²C interface. There is no need to separately download internal calibration coefficients and have the host microcontroller conduct complicated compensation calculations. Two selectable modes (Sleep and Update) and an external "Measurement Ready" pin ensure operational flexibility suitable for
a wide range of applications.
