Default That Corporation 1200 , 1203 , 1206 circuits

Anyone know of any real world applications of this opamp?
Id like to design an line receiver / input buffer circuit around this chip.

After reading all the documentation and forums, i still have 2 questions.

From input to output, does this chip invert signal?

How could a variable gain option be added to the THAT 1200 basic circuit?

Thanks in advance

Have you visited these two forums?

http://www.waynekirkwood.com/forum/p...1a7523659c4f53
http://www.proaudiodesignforum.com/f...wforum.php?f=1

They are sort of interlinked and neither has much activity but the little activity they have is often about THAT chips.

The data sheets from THAT have everything you'd ever want to know about their chips. They are extremely complete. They also have white papers that talk about their patents.
