When looking at the attached schematic, I see a diff-amp with an inverting stage to produce diff-out at near unity gain. Where's the "active attenuation" that That Corp is referring to?
[quote author=That Corp Datasheet for THAT5171, pg 10]For better distortion performance with high- quality A/D converters, and to improve common-mode rejection, consider circuits like the one in Figure 6. The active (buffered) attenuator provides differential drive to the ADC, which improves performance.[/quote]
Here's the link to the datasheet (page 10, first paragraph): http://www.thatcorp.com/datashts/THAT_5171_Datasheet.pdf
Am I missing something? ???
