DESCRIPTION

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

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.
