OutSmarts® Balanced Line Driver ICs

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.

APPLICATIONS

• Differential Line Drivers

• A/D converter Drivers

Analog Secrets Your Mother Never Told You (1528k)

Originally presented at the 123rd AES Convention, this seminar provides tips and techniques to achieve optimal performance in the analog signal path. Topics covered range from inputs (balanced line and mic level) to outputs (balanced to single-ended), and include analog signal processing (VCAs, RMS detection, and Analog Engines).
1606/1646 Demo Board - The THAT 1606/1646 Demonstration System (US$100) allows an engineer to test the performance of a THAT 1606 or 1646 IC quickly and easily. The 1606/1646 Demo Board is self-contained circuit board with XLR connectors for signal input and output and a 3-pin header for connection to an external regulated DC power supply (not included). See the 1606/1646 DEMO Datasheet for more information.

1606 Surface Mount Adapter Board - For our integrated circuits which are only available in surface mount packages THAT Corporation offers adapter boards which allow one of these surface-mount ICs to interface to a circuit board via traditional thru-hole mounting. These adapters make it easy for a design engineer to evaluate our surface-mount products on a prototype board without having to employ SMT technology. Adapter boards are available to qualified applicants.

Line Driver Comparison Chart - The 1646 is pin-compatible with the TI DRV134 and DRV135, as well as the Analog Devices SSM2142. Both the 1646 and 1606 offer superior performance. See here a chart of the features and specifications of our OutSmarts line drivers to competing, and in some cases pin-compatible, components.

Line Driver Clipping Behavior - THAT 1646 and 1606 Line Drivers use a dual feedback-loop design that prevents the excessive ground currents typical of cross-coupled output stages (CCOS) when clipping into single-ended loads. In these clipping performance graphs you can see the superior clipping behavior of OutSmarts technology versus our competitor's line drivers.
