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.
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
performance for IF amplification in wireless
communications systems by having IMD3 performance of
−80 dBc, OIP3 of 41 dBm, and a noise figure of 11 dB, all at
100 MHz with a gain +10 V/V, while driving a 2-VPP
envelope into a 100-Ω load.
The THS3201 is offered in a 5-pin SOT−23, 8-pin SOIC,
and an 8-pin MSOP with PowerPAD packages.
