I am working on czl-601 load cell which gives me maximum o/p of 24 mv if i give supply voltage of 12 v(2mv/v ). I want this to be interfaced to lpc2148 inbuilt ADC, I need to amplify this 24 mv signal to 3.3 volt , i used opamp741 in inverting amplifier mode with gain of (3300/24==>137.5), but without connecting anything at opamp input it is giving output of 1.8 volt , how ca i achieve 0 to 3.3 volt by 0 to 24mv ? suggest any circuit ?
