DESCRIPTION

The THS3202 is part of the high performing current

feedback

amplifier

family

developed

in

BiCOM−

ΙΙ

technology. Designed for low-distortion with a high slew

rate of 9000 V/

µs, the THS320x family is ideally suited for

applications driving loads sensitive to distortion at high

frequencies.

The THS3202 provides well-regulated ac performance

characteristics

with

power

supplies

ranging

from

single-supply 6.6-V operation up to a 15-V supply. The

high unity gain bandwidth of up to 2 GHz is a major

contributor to the excellent distortion performance. The

THS3202 offers an output current drive of

±115 mA and a

low differential gain and phase error that make it suitable

for applications such as video line drivers.

The THS3202 is available in an 8 pin SOIC and an 8 pin

MSOP with PowerPAD

 packages.
