Purpose The purpose of the lab was to test the gain bandwidth of TLC 2274 and an AD817 as well as the slew rate of a TLC 2274 op amp. Approach and Results The same circuit was used to test the gain bandwidth of the TLC 2274 and AD817 op amps. A voltage divider was used to get a voltage of 10mVrms @ 100 Hz. A 1kΩ resistor was placed in series with a 100Ω resistor. The input was then adjusted so that 10mVrms went into the non- inverting pin of the op amp. An Ri resistor of 1kΩ and a feedback resistor of 220kΩ was fed from the inverting pin of the op amp to the output. +-5 Vdc was supplied to op amps and 0.1uF coupling capacitors were used. FIGURE NOT ONLINE*** Figure 1: Closed Loop Frequency Response TLC 2274 FIGURE NOT ONLINE*** Figure 2: Closed Loop Frequency Response AD817 DMM was connected to the output of the op amps and the frequency of the input signal ein was gradually increased. With each increase of frequency, the DMM was placed at ein to make sure that 10mVrms was still going into the op amp. The gain was measured by taking the output
