The circuit does not have enough differential gain

Component tolerances and input bias current mismatch can influence the circuit performance

The environment is too noisy

The circuit has too much gain

A_{c} = \dfrac{V_{o}}{V_{in2} - V_{in1}}

A_{c} = \dfrac{V_{o} \times V_{cm}}{V_{in2}}

A_{c} = \dfrac{V_{o}}{V_{cm}}

A_{c} = \dfrac{V_{o}}{V_{in1} + V_{in2}}
