InGenius High-CMRR Balanced Input Line Receiver ICs

he THAT1200 series InGenius balanced line receivers overcome a serious limitation of conventional balanced input stages: 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 indistin- guishable from desired, balanced signals By THAT Corporation
