OutSmarts™ Balanced Line Drivers
The 1600 series is a family of improved active-balanced floating-output driver ICs intended for use in pro audio applications. Compared to competing integrated solutions, the 1600 series offers at least 3dB more dynamic range and improves signal quality under demanding output-drive conditions. The 1600 family uses THAT’s patented OutSmarts™ technology, a dual-feedback-loop design that prevents the excessive ground currents that flow in traditional cross-coupled output stages when clipping into single-ended loads.
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.
