6.3.1.2 Auxiliary Amplifier

The LMH6518 has a second output amplifier that was designed to provide a trigger signal when used as an oscilloscope AFE. The auxiliary amplifier has all of the features of the output amplifier and provides a duplicate signal for use in trigger circuits. The auxiliary amplifier has a common mode voltage control pin which sets the output common mode of the amplifier.
