Hello, I have a problem with differential amplifier. I use LMC6484 (http://www.ti.com/lit/ds/symlink/lmc6484.pdf) op amp to project differential amplifier (schematic in the picture). Resistors values are R1=R3=100k and R2=R4=1k, so theoretically gain should be about 100. My object for this project is to amplify signal from Honeywell pressure transducer (https://stevenengineering.com/tech_support/PDFs/31DTMAIN.pdf) which voltages are about 0-30mV, to voltages for adc. I connect this circuit on breadboard and connect my pressure transducer signal+ and signal- wires to differential amplifier + and - inputs. Voltage between pressure transducer data pins, when there is no pressure is about 30mV, and in differential amplifier output i get 4,6V, but when I apply pressure to transducer and transducer output voltage is increasing, there is no change in amplifier output - still 4,65V. Maybe someone know solution for this problem?
