    ... The LM6172 is a dual high speed voltage feedback amplifier unity-gain stable and provides excellent DC and AC per- formance. With 100MHz unity-gain bandwidth, 3000V/μs slew rate and 50mA of output current per channel, the LM6172 of- fers high performance in dual amplifiers; yet it only consumes 2.3mA of supply current each channel. ...

    ... The combination of an amplifier's input capacitance with the gain setting resistors adds a pole that can cause peaking or oscillation. To solve this problem, a feedback capacitor with a value 20159451 can be used to cancel that pole. For LM6172, a feedback ca- pacitor of 2pF is recommended. pensation circuit. 20159452 FIGURE 4.
