Typical Applications
(Also see Application Note AN550)
Application 1
High power amplifiers and buffers are in use in a wide variety
of applications. Many times the “high power” capability is
needed to drive large capacitive loads as well as low value
resistive loads. In both cases the final driver stage is usually a
power transistor of some type, but because of their inherently
low gain, several stages of pre-drivers are often required. The
HA-2541, with its 10mA output rating, is powerful enough to
drive a power transistor without additional stages of current
amplification. This capability is well demonstrated with the
high power buffer circuit in Figure 3.
The HA-2541 acts as the pre-driver to the output power
transistor. Together, they form a unity gain buffer with the
ability to drive three 50
coaxial cables in parallel, each with
a capacitance of 2000pF. The total combined load is 16.6
and 6000pF capacitance.
Application 2
VIDEO
One of the primary uses of the HA-2541 is in the area of
video
applications.
These
construction, synchronization addition and removal, as well
as signal modification. A wide bandwidth device such as the
HA-2541 is well suited for use in this class of amplifier. This,
however, is a more involved group of applications than
ordinary amplifier applications since video signals contain
precise DC levels which must be retained.

The addition of a clamping circuit restores DC levels at the
output of an amplifier stage. The circuit shown in Figure 4
utilizes the HA-5320 sample and hold amplifier as the DC
clamp. Also shown is a 3.57MHz trap in series, which will
block the color burst portion of the video signal and allow the
DC level to be amplified and restored.
