THAT 1646 是新一代音频差分线路驱动器,其性能优于传统的交叉耦合单片设计。


此外,它还采用获得专利的 OutSmarts™ 技术,这是一种双反馈回路设计,可防止在切入单端负载时出现交叉耦合输出级典型的过大接地电流。

THAT1646P08-U 是 DRV134/SSM2142 的合适替代品,而 THAT1646W16-U 是 SSM2142/DRV134 的合适替代品。

The THAT 1646 is a new generation of audio differential line driver with improved performance over conventional cross-coupled monolithic designs.

It exhibits low noise and distortion, high slew rate, stability under difficult loads, wide output swing, and have outputs which are short-circuit protected.

In addition it incorporates patented OutSmarts™ technology, a dual feedback-loop design that prevents the excessive ground currents typical of cross-coupled output stages when clipping into single-ended loads.

The THAT1646P08-U is a suitable replacement for the DRV134/SSM2142, while the THAT1646W16-U is a suitable replacement for the SSM2142/DRV134.
