GENERAL DESCRIPTION
The BUF04 is a wideband, closed-loop buffer that combines
state of the art dynamic performance with excellent dc
performance. This combination enables designers to maximize
system performance without any speed versus dc accuracy
compromises.
Built on a high speed Complementary Bipolar (CB) process for
better power performance ratio, the BUF04 consumes less than
8.5 mA operating from 5 V or 15 V supplies. With a 2000 V/ s
min slew rate, and 100 MHz gain bandwidth product, the
BUF04 is ideally suited for use in high speed applications where
low power dissipation is critical.
Full 10 V output swing over the extended temperature range
along with outstanding ac performance and high loop gain
accuracy makes the device useful in high speed data acquisition
systems.

High slew rate and very low noise and THD, coupled with wide
input and output dynamic range, make the BUF04 an excellent
choice for video and high performance audio circuits.
The BUF04’s inherent ability to drive capacitive loads over a
wide voltage and temperature range makes it extremely useful
for a wide variety of applications in military, industrial, and
commercial equipment.
The BUF04 is specified over the extended industrial (–40 C to
+85 C) and military (–55 C to +125 C) temperature range.
BUF04s are available in plastic and ceramic DIP plus SO-8
surface mount packages.

... Often, high frequency filters are needed for these applications; however, there are few op amps that exhibit the high open-loop gain and wide unity-gain crossover frequency required for these applications.

... An example of one such application is illustrated in Figure 39. In this circuit, the BUF04s are required to drive a doubly terminated This type of a load for a single BUF04 would certainly cause a power dissipation problem.
