The THS3215 combines the key signal-chain components required to interface with a complementary-current output, digital-to-analog converter (DAC). The flexibility provided by this two-stage amplifier system delivers the low distortion, dc-coupled, differential to single-ended signal processing required by a wide range of systems.The input stage buffers the DAC resistive termination, and converts the signal from differential to single-ended with a fixed gain of 2 V/V. The differential to single-ended output is available externally for direct use, and can also be connected through an RLC filter or attenuator to the input of an internal output power stage (OPS). The wideband, current-feedback, output power stage provides all pins externally for flexible gain setting. An internal 2 × 1 multiplexer (mux) to the output power stage noninverting input provides an easy means to select between the internal differential-to-single-ended stage (D2S) output or an external input. An optional on-chip midsupply buffer provides a wideband, low-output-impedance source for biasing during single-supply operation through the signal-path stages. This feature provides very simple biasing for single-supply, ac-coupled applications operating up to a maximum 15.8-V supply. An external input to this buffer allows for a dc error-correction loop, or a simple output dc offset feature. A companion device, theTHS3217, provides the same functional features at higher quiescent power and bandwidth. The THS3215 and THS3217 support the emerging high-speed Texas Instruments DACs for AWG applications, such as theDAC38J82.

The THS3491 current feedback amplifier (CFA) provides a new level of performance for applications requiring the lowest distortion at high output power levels from DC through values greater than 100 MHz at 100-Ω loads. Although specified at a gain of 5 V/V, this current feedback design holds near constant bandwidth and distortion over a wide range of gains. The 8000 V/µs of slew rate delivers an output of 10 VPPinto demanding loads with low distortion through 100 MHz. The 900-MHz, small-signal bandwidth delivers a low overshoot of less than 1.5% for a 10-V step, and rise and fall times of less than 1.3 ns. Peak output current drive values greater than 500 mA enable driving heavy capacitive loads with fast signals. New designs benefit from the lowest distortion using the VQFN-16 (RGT) package, whereas the 8-pin HSOIC (DDA) package (with PowerPAD™) upgrades existingTHS3091orTHS3095designs. Lower output headroom for the THS3491 provides more output swing on the same ±15-V supplies versus legacy THS3091 or THS3095 options.
