THAT Corporation 1200 Series InGenius® Balanced Line Receiver ICs

THAT Corporation 1200 Series InGenius^® High-CMRR Balanced Input Line Receiver ICs are designed to overcome poor common-mode rejection in real-world applications that conventional balanced input stages provide. Traditional input stages fail to live up to their CMRR specs when fed from even slightly unbalanced source impedances.

The THAT Corp 1200 Series InGenius Balanced Line Receiver ICs implement the patented InGenius input stage with clever bootstrapping to raise its common-mode input impedance into the megohm range without the noise penalty from the obvious solution of using high-valued resistors. Similar to transformers, InGenius line receivers maintain a high CMRR over a wide range of source impedance imbalances, even when fed from single-ended sources. Unlike transformers, the 1200 series wide bandwidth solid-state devices offer dc-coupling, low distortion, and transparent sound in a small package.
