I lookfor a pressure sensor that convert pressure to frequency .
The output of the device should be a 50% duty-cycle square wave with a frequency
that is proportional to the absolute pressure of the device.
Which embedded sensor integrated circuit can help me in this way??

| Most pressure sensors output voltage. Can you take an output voltage of the pressure sensor and convert it to frequency with a frequency to voltage (F/V) convertere IC?

trust me there is no pressure sensor which is going to do that..
pressure sensors always give 0-5 or 0-10 vdc or 4-20 ma ..you should figure out a circuit which is going to do that
