DESCRIPTION
The THAT 1606 and 1646 are a new generation of monolithic differential line drivers offering improved performance over conventional cross-coupled designs. Based on a high-performance, fully differential op amp and laser-trimmed thin-film resistors, both families exhibit low noise and distortion, high slew rate, and wide output swing. The parts are stable when driving difficult loads, and have short-circuit protected outputs. Both models incorporate THAT's patented OutSmarts technology. Outsmarts is a dual feedback-loop design that prevents the excessive ground currents typical of cross-coupled output stages (CCOS) when clipping into single-ended loads.
The 1646 is pin-compatible with the TI DRV134 and DRV135, as well as the Analog Devices SSM2142.
The unique 1606 offers differential inputs, a space-saving connection to minimize output dc offset, and comes in a special 16-pin QSOP which improves power dissipation without sacrificing footprint.
描述
这1606和1646是新一代的单片差分线路驱动器，提供了比传统的交叉耦合设计更好的性能。基于高性能，全差分运算放大器和激光微调薄膜电阻，两个家庭都具有低噪声和失真，高转换率和宽输出摆幅。当驱动困难负载时，部件稳定，并具有短路保护输出。这两种模式结合的专利技术，打败了。智取是双反馈回路的设计，防止过度的接地电流的典型交叉耦合输出阶段（CCOS）当裁剪成单端负载。
1646是TI drv134和drv135引脚兼容，以及模拟设备SSM2142。
独特的1606提供差分输入，节省空间的连接来减少输出直流偏移，是在一个特殊的16引脚QSOP提高功耗而牺牲的足迹。
