Since my sources are all high level, I plan on building a preamp using an op amp in voltage follower mode. I know that when operating such a device with a gain of more than 1, the output will be in Class AB and a device such as a pull down resistor is required to force the output into class A. However, I was told that in the voltage follower configuration the output remains in Class A. I haven't been able to verify this so am asking the question here. If it's relevant, the device in question is an Analog Devices AD845 with the output taken from pin 6.
