DESCRIPTION
The
THS3201
is
a
wide-band,
high-speed
current-feedback amplifier, designed to operate over a
wide supply range of
鹵3.3
V to
鹵7.5
V for todays high
performance applications.
The wide supply range combined with distortion as low as
鈭?4 dBc at 10 MHz, plus an extremely high slew rate of
10500 V/碌s makes the THS3201 ideally suited for arbitrary
waveform driver applications. The distortion performance
also enables driving high-resolution and high-sampling
rate ADCs. Moreover, the gain of +2 bandwidth of 850
MHz, combined with a 0.1 dB flatness of 380 MHz makes
the THS3201 ideal for broadcast video and HDTV
applications. The THS3201 also offers excellent
performance
for
IF
amplification
in
wireless
communications systems by having IMD
3
performance of
鈭?0 dBc, OIP
3
of 41 dBm, and a noise figure of 11 dB, all at
100 MHz with a gain +10 V/V, while driving a 2-V
PP
envelope into a 100-鈩?load.
The THS3201 is offered in a 5-pin SOT鈭?3, 8-pin SOIC,
and an 8-pin MSOP with PowerPAD錚?packages.
