Description for the THS3491
The THS3491 current feedback amplifier (CFA) provides a new level of performance forapplications requiring the lowest distortion at high output power levels from DC through valuesgreater than 100 MHz at 100-Ω loads. Although specified at a gain of 5 V/V, this current feedbackdesign holds near constant bandwidth and distortion over a wide range of gains.
The 8000 V/µs of slew rate delivers an output of 10 VPP intodemanding loads with low distortion through 100 MHz. The 900-MHz, small-signal bandwidth delivers alow overshoot of less than 1.5% for a 10-V step, and rise and fall times of less than 1.3 ns. Peakoutput current drive values greater than 500 mA enable driving heavy capacitive loads with fastsignals.
New designs benefit from the lowest distortion using the VQFN-16 (RGT) package, whereasthe 8-pin HSOIC (DDA) package (with PowerPAD™)upgrades existing THS3091 orTHS3095 designs. Lower output headroom forthe THS3491 provides more output swing on the same ±15-V supplies versus legacy THS3091 or THS3095options.
NEW - You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.
A custom reel
is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.
Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.TI often ships
devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
