THAT1206P08-U (THAT CORPORATION)

The THAT1206P08-U is an InGenius® high-CMRR balanced input Line Receiver overcome a serious limitation of conventional balanced input stages of poor common mode rejection in real-world applications. While conventional input stages measure well in the lab and perform well on paper, they fail to live up to their CMRR specs when fed from even slightly unbalanced source impedances - a common situation in almost any pro sound environment. This is because conventional stages have low common-mode input impedance, which interacts with imbalances in source impedance to unbalance common-mode signals, making them indistinguishable from desired, balanced signals. The patented InGenius input stage uses clever bootstrapping to raise its common-mode input impedance into the mega ohm range without the noise penalty from the obvious solution of using high-valued resistors.
