InGenius® High-CMRR Balanced Line Receiver ICs

InGenius common mode rejection vs. imbalance

DESCRIPTION

The THAT 1200-series InGenius® high-common mode rejection balanced line receiver IC overcomes 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 line impedances — a common situation in almost any pro audio environment.

APPLICATIONS

• Balanced Audio Line Receivers
• Instrumentation Amplifiers
• Differential Amplifiers
• Transformer Front-End Replacements
• ADC Front-Ends
