Based on a high-performance, fully differential opamp 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.
Designed from the ground up in THAT's complementary dielectric isolation process, both models incorporate THAT's 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.
As a result, THAT's topology prevents the loss of common-mode feedback that plagues common CCOS designs when clipping into single-ended loads.
This avoids excessive ground currents that would otherwise upset power supplies and create additional distortion, even in adjacent channels.
The 1646 is pin-compatible with the TI DRV134 and DRV135, as well as the Analog Devices SSM2142.
The 1606 offers an advanced co...
