3 Description
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
VPP into 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
existing THS3091 or THS3095 designs. Lower output
headroom for the THS3491 provides more output
swing on the same ±15-V supplies versus legacy
THS3091 or THS3095 options.
