... The op amp is designed to sense the difference between the voltage signals applied to its two inputs (v2-v1), and multiply this by a number A, and cause the resulting voltage A (v2-v1) to appear at the output terminal relative to ground. Note that v1 and v2 are also implied to be relative to ground ...

CIRCUIT FUNCTION AND BENEFITS
... Data acquisition systems with wide dynamic range often need some method for adjusting the input signal level to the analog-todigital converter (ADC). In order to get the most from an ADC, the maximum input signal should match its full-scale voltage. This is achieved by implementing a programmable ga ...

Negative feedback
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.Whereas positive feedback tends to lead to instability via exponential growth, oscillation or chaotic behavior, negative feedback generally promotes stability. Negative feedback tends to promote a settling to equilibrium, and reduces the effects of perturbations. Negative feedback loops in which just the right amount of correction is applied with optimum timing can be very stable, accurate, and responsive.Negative feedback is widely used in mechanical and electronic engineering, but it also occurs naturally within living organisms, and can be seen in many other fields from chemistry and economics to physical systems such as the climate. General negative feedback systems are studied in control systems engineering.
