1606 /46 Balanced Line Driver ICs

Regular Production now .......

The THAT 1606/1646 (formerly the THAT 1430/1420) are a new generation of audio differential line drivers with improved performance over conventional cross-coupled monolithic designs. Both models exhibit low noise and distortion, high slew rate, stability under difficult loads, wide output swing, and have outputs which are short-circuit protected.

The 1646 is pin-compatible with the TI  DRV134 and DRV135, as well as the Analog Devices SSM2142.

The 1606 offers an advanced common-mode offset voltage reduction scheme, which requires a small single capacitor instead of the two electrolytics required by the 1646 and its pin-compatible cousins. Additionally, the 1606 features differential inputs in a space-saving 16-pin QSOP package. Both parts offer +6 dB gain.

In addition both models incorporate 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.

Designed from the ground up in THAT's complementary dielectric isolation process, both models incorporate THAT's patented OutSmarts 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.

Where minimum parts count is desired, the THAT 1606 further improves over existing designs by requiring only a single film or ceramic capacitor to achieve low common-mode output offset  voltage.

All 1606/1646 parts are lead-free.

OutSmarts Identity Program

- Audio manufacturers who include OutSmarts in their products are providing a real, audible benefit to their customers. Like the ‘Intel Inside’ campaign, the OutSmarts Identity program helps participating manufacturers get this point across to their customers.
 

With increasing demand for its OutSmarts line of balanced line driver ICs, THAT Corporation has announced details of a new OutSmarts Identity Program.  Participating manufacturers can mark their OutSmarts-equipped products with a logo which will be supplied to them at no charge. Much like the 'Intel Inside' campaign, the goal of the OutSmarts Identity Program is to help manufacturers provide a real, audible benefit to their customers, and simultaneously promote end-user awareness of the benefits of OutSmarts."
