... V to −10 V with no modifications. The shunt voltage is amplified by a factor of 49.7 using U1A, where R3/R2. The zero-drift ADA4051-2 offset voltage (15 µV maximum) and does not contribute significant error to the measurement. A full-scale shunt voltage produces a full-scale output voltage from U1A of 2 ...

... If this offset is added, then R3 should be reduced to 46.4 kΩ to maintain a full-scale ADC input voltage of 2.5 V for shunt voltage. Without the offset, the ADA4051-1 output will become nonlinear for output voltages less than about 40 mV. CIRCUIT EVALUATION AND TEST ...
