PRODUCT DESCRIPTION


The S121 system-in-a-package (SIP) solution comprises of aresistive bridge type pressure sensor and a 24-bit ADC for high resolution and accurate pressure measurements. The fully calibrated pressure and temperature compensated digital output makes the S121 solution simple to use.
The S121 includes internal calibration logic that 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 perform complicated compensation calculations.
