InGenius® THAT1203 平衡线路接收器旨在克服传统平衡级的严重限制之一——即实际应用中共模干扰差。

虽然传统的输入级在纸面上可能具有良好的抑制特性,但即使从轻微不平衡的源阻抗馈送,它们的性能也会很差 - 这是演播室、现场声音和广播环境中极为常见的情况。

THAT1203 即使从单端源馈电,也能实现高 CMRR,这是因为其独特的自举电路将共模输入阻抗提高到兆欧范围,而不会产生相应的噪声损失。

演示板 THAT1200DEMO 适用于本产品。

The InGenius® THAT1203 balanced line receiver is designed to overcome one of the serious limitations of conventional balanced stages - namely poor common mode interference in real-world applications.

While conventional input stages may possess good rejection characteristics on paper, they perform poorly when fed from even slightly un-balanced source impedances - an extremely common situation in studio, live sound and broadcast environments.

The THAT1203 achieves a high CMRR even when fed from a single-ended source as a result of its unique bootstraping circuitry that raises the common-mode input impedance into the megohm range without a commensurate noise penalty.

Demonstration Board THAT1200DEMO is available for this product.
