DESCRIPTION
The THS3201 is a wideband, high-speed
current-feedback amplifier, designed to operate over
a wide supply range of ±3.3 V to ±7.5 V for today's
high performance applications.
The wide supply range, combined with low distortion
and high slew rate, makes the THS3201 ideally
suited for arbitrary waveform driver applications. The
distortion performance also enables driving
high-resolution
and
high-sampling
rate
analog-to-digital converters (ADCs).
Its high voltage operation capabilities make the
THS3201 especially suitable for many test,
measurement, and ATE applications where lower
voltage devices do not offer enough voltage swing
capability. Output rise and fall times are nearly
independent of step size (to first-order
approximation), making the THS3201 ideal for
buffering small to large step pulses with excellent
linearity in high dynamic systems.
The THS3201 is offered in a 5-pin SOT-23, 8-pin
SOIC, and an 8-pin MSOP with PowerPAD™
packages.
