An Example of How Differences in Input Signal Level Can Introduce Gain Errors Under zero signal conditions, there is no output signal and no resistor heating. When an input signal is applied, however, an amplified voltage appears at the op amp output. When the amplifier is operating with gain, Resistor R1 will be greater than R2. This means that there will be more voltage across R1 than across R2.

Single-Supply Operation Single-supply operation has become an increasingly desirable characteristic of a modern in-amp. Many present day data acquisition systems are powered from a single low voltage supply. For these systems, there are two vitally important characteristics. First, the in-amp’s input range should extend between the positive supply and the negative supply (or ground). Second, the amplifier’s output should be rail-to-rail as well, providing an output swing to within 100 mV or less of either supply rail or ground.
