Access to an amplifier in the Analog Output path

[rpursley8]

I would like to have an programmable gain amplifier in the analog output path that I can use to adjust the amplitude of an output signal.  In control applications, this would be much better than having to stop a continuous task, reload the data with a new amplitude, and start the task again.

Ideally, for some of my applications, it would be nice to be able to generate a basic waveform scaled to +/- 1V and then have a property that I can write to while the task is running to set the gain.

And you get better digital amplitude resolution by loading a waveform that spans the full DAC output range.

One way to accomplish amplitude scaling is to use a device that supports a DAC Reference Voltage.  Then use the second DAC output as a control voltage to set the amplitude via that Reference Voltage of the first DAC.
