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.
