Description
The HFA-0005 is an all bipolar op amp featuring high slew
rate (420V/µs), and high unity gain bandwidth (300MHz).
These features combined with fast settling time (20ns) make
this product very useful in high speed data acquisition
systems as well as RF, video, and pulse amplifier designs.
Other outstanding characteristics include low bias currents
(15µA), low offset current (6µA), and low offset voltage
(6mV). These high performance characteristics are achieved
with only 40mA of supply current.
The HFA-0005 offers high performance at low cost. It can
replace hybrids and RF transistor amplifiers, simplifying
designs
monolithic construction. To enhance the ease of design, the
HFA-0005 has a 50Ω ±20% resistor connected from the
output of the op amp to a separate pin. This can be used
when driving 50Ω strip line, microstrip, or coax cable.
