I am trying out the AD8293G80 as a possible replacement for our current IA. The IA is used to amplify the output of a pressure sensor and pass the output to an A/D. I have hooked the AD8293 up as indicated in the data sheet but the output (either pin 4 or pin 6) reads 5.1 mV and doesn't change for any change in input. The input signal from the pressure sensor varies between 0 and 10 mV. The common mode voltage is about 2.44 V. The power supply voltage is 5V. I tried another AD8293 and got a similar constant output of 5.6 mV. The pressure sensor is working properly as is the A/D. Do you have any suggestions as to what might be wrong?
