Hi,
I am curious how quickly the power down function of the LMH6629 operates (how fast off and how fast on). I was hoping to use the power down function to save the amp from going into unnecessary saturation/ power waste. There is a very small AC signal of interest that the amp needs to amplify with very high gain, but the issue is that it only comes after a much larger AC signal that is NOT of interest and will certainly saturate the amp if left on. I am using a microcontroller to perform the timing. It basically goes: 100ms of a much larger signal to 400ms of very small signal of interest and this cycle repeats hundreds of times. I am not sure if the power down function was meant to be cycled/used like that.
I realize I could also use some combo of transistors controlled by the microcontroller to block the larger AC signal from the amp's inputs as well but I thought it might be easiest to use this power down function. Any advise is appreciated!
