I'm working on a circuit which uses a Honeywell NSC pressure sensor, uncompensated and unamplified. Looking over the specs for this, I'm having a bit of difficulty understand full scale span (aka full scale output) that is listed for the sensor.
The typical value for full scale output in the datasheet is listed as 25.9 mV / V. The sensor will operate at 5V.
My question is, does the sensor actually put out 0 to 25.9 mV / V, or is the range increased by 5 due to the excitation voltage? Meaning, 0 to 129.5 mV / V output.
I'm trying to determine the minimum and maximum output voltage from the pressure sensor so that I can design an op-amp circuit which will increase the signal to be read by my AVR's ADC.
