Based on figure 2, connect different values of capacitors from pin 5 of the OP97 to ground. Try values in the range of 100 pF to 10 nF and see how your results compare to figure 2. | Based on figure 2, connect different values of capacitors from pin 5 of the OP97 to ground.

- | From your parts kit substitute other op-amp models and make the same frequency response plots and calculate the GBW. Be sure to properly connect each version according to its package and pinout. Single op-amps tend to have similar pinouts but not the same a dual or quads. Compare your measured results to each amplifier’s datasheet specification for GBW. | + | From your parts kit substitute other op-amp models and make the same frequency response plots and calculate the GBW.

Note: the ADTL082 amplifier requires a minimum of 8 volts for the power supply and will not operate properly with just the +5 Volts available from the ALM1000. The minus supply of the ADTL082 can be connected to a 3 V battery connected from ground ( battery + ) to pin 4 ( -Vs ) such that -3V is provided. | Note: the ADTL082 amplifier requires a minimum of 8 volts for the power supply and will not operate properly with just the +5 Volts available from the ALM1000.
