its working getting -2mV without any pressure and it increase gradually as pressure increases.
I have change the pressure sensor , i think i have damage the first one.
thank you everyone,
i am still working on it as the output is too noisy,
Thank you for your response,
this is the application note of the pressure sensor, I implement the same circuit which is shown on the page 10 , with little modification i.e
1)giving GND to Reference input
2) R6=10Kohms not 1Kohms which give me gain of 3...
I am using a pressure sensor(2smpp-02) whose output voltage range from 0-30mV ,wanted to amplify the it so that i can process it with micro-controller,
can i avoid using instrumentation amplifier ?? as for it costing reason.
