Overview

The devices include a piezoresistive pressure sensor and an ADC-Interface IC. The  3-wire  serial  interface ensures  simple  communication  with  any  microcontroller. The devices provide digital pressure and temperature information as 16-Bit data word each. In addition 64-Bit of individually calibrated compensation  coefficients  are  stored  allowing  for  a  highly accurate   software   compensation   of   process   spread   and temperature effects. The devices have a very low standby current and automatically enter  power  down  mode  after  each  conversion.  The  optimum compromise of refresh rate and average current  consumption can be defined by the application software.
