LME49724: using dc servo to remove offset voltage on the outputs

Hello, 

Our team is looking into this thread and will respond as soon as possible.

Ok - thank you, Justin.

Hi Vinnie,

I would suggest to use the available simulation models to verify the servo amplifier on the feedback loop is not affecting the device operation. I haven't seen these servo amplifiers in differential amplifiers like LME49724.

Hi Ivan,

Can you show this to someone in the engineering team that is familiar with using a servo with a differential amp like this?  
I don't believe I am breaking any new ground with this idea ;-)

The input is a single-ended (summing amp) via R46 and R47.

Ltspice simulations look good, but I was just hoping that someone very familiar with the LME49724 (and servos) can chime in.

Thank you,

Vinnie

Vinnie,

Will ask precision amplifiers team to take a look if possible, this is not common in audio applications.
However as long as simulations are OK I would say it is fine to implement.

Ok - thank you, Ivan!
