THAT1646S08-U

芯片, 平衡线路驱动器

The 1646S08-U is a balanced Line Driver IC monolithic audio differential line drivers offering improved performance over conventional cross coupled designs. Based on a high-performance, fully differential operational amplifier and laser-trimmed thin-film resistors, both families exhibit-bit 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. Designed from the ground up in complementary dielectric isolation process, both models incorporate THATs patented OutSmarts1 technology. This 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. OutSmarts uses two individual negative-feedback loops to separately control the differential output voltage and common mode output currents, making the designs inherently more stable and less sensitive to component tolerances than common CCOSes.
