Theory

Inverting: $A_v = -\dfrac{R_f}{R_1}$ Non-Inverting: $A_v = 1 + \dfrac{R_f}{R_1}$

Voltage Follower: $A_v = 1$ Summing: $V_{out} = -R_f\!\left(\dfrac{V_1}{R_1}+\dfrac{V_2}{R_2}\right)$

Differentiator: $V_{out} = -R_f C \dfrac{dV_{in}}{dt}$ Integrator: $V_{out} = -\dfrac{1}{RC}\int V_{in}\,dt$

GBW product: $\text{BW} = \dfrac{\text{GBW}}{|A_v|}$ (GBW = 1 MHz assumed)

Applications: Op-amps are fundamental in sensor signal conditioning, active filter design, and ADC front-ends. Differentiators convert accelerometer velocity signals to acceleration; integrators are used in strain-gauge charge amplifiers and control loops.
