Unity Gain Bandwidth: 1.8 GHz
The
THS3201
is
a
wide-band,
high-speed
current-feedback amplifier, designed to operate over a
wide supply range of 3.3 V to 7.5 V for todays high
performance applications.
High Slew Rate: 10500 V/µs
Distortion at 100 MHz: (G = 10 V/V,
R = 100 Ω, 2-V envelope)

The wide supply range combined with distortion as low as
−74 dBc at 10 MHz, plus an extremely high slew rate of
10500 V/µs 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
