inputs or 75Ω systems and cables.
DESCRIPTION
The BUF600 and BUF601 are monolithic open-loop
unity-gain buffer amplifiers with a high symmetrical
slew rate of up to 3600V/µs and a very wide band-
width of 320MHz at 5Vp-p output swing. They use a
complementary bipolar IC process, which incorpo-
rates pn-junction isolated high-frequency NPN and
PNP transistors to achieve high-frequency performance
previously unattainable with conventional integrated
circuit technology.
The broad range of analog and digital applications
extends from decoupling of signal processing stages,
impedance transformation, and input amplifiers for
RF equipment and ATE systems to video systems,
distribution fields, IF/communications systems, and
output drivers for graphic cards.

Their unique design offers a high-performance alter-
native to expensive discrete or hybrid solutions.
The BUF600 and BUF601 feature low quiescent
current, low input bias current, small signal delay time
and phase shift, and low differential gain and phase
errors.

The BUF600 with 3mA quiescent current is well-
suited for operation between high-frequency
processing stages. It demonstrates outstanding perfor-
mance even in feedback loops of wide-band amplifiers
or phase-locked loop systems.
