Power_op_amp_follower_inverter

This circuit shows an LM12 power op amp connected as both a follower and an inverter, with input compensation to reduce bandwidth and increase stability. Figure 10-46B shows typical characteristics for the LM12, which is compensated for unity-gain feedback, and a small-signal bandwidth of 700 kHz. The LM12 is housed in a TO-3 package and requires a heatsink (because of the high power). Figure 10-46C shows the heatsink surface area required for temperature rise and power dissipation.
