The pressure sensor input variants about the pressure, temperature and material. The signal may need amplification so there has to be an amplifier added.
The input bias currents of this type of amplifier is usually below 100 pA, it should be fine as long as the feedback resistor value is below 1 GΩ. Specified excitation voltage for all standard ICP sensors and amplifiers is generally within the range of 18 to 30 volts.
