ANALOG
DEVICES BUF-03's Simplified Schematic
General Description
The BUF-03 is the first
very high-speed monolithic voltage follower.
Featuring performance
previously unobtainable in a monolithic unit, it offers a combination of
both exceptional speed and excellent input/output specifications. Implemented
in an open-loop circuit employing source followers and emitter followers,
the BUF-03 utilizes a quasi-quad FET input structure to optimize both speed
and D. C. input characteristics.
On-Chip zener-zap trimming
is used to achieve low offset voltage while careful biasing throughout
results in excellent gain linearity over the full input voltage range
Applications for which
the BUF-03 is well-suited include high-speed line drivers ...
PCB
layout (Gold plated with silk print parts installations)
PCB
to use in general power supply applications
In case you need a power
supply PCB, the BUF-03 will very well to suit an applications also for
DC +/- power supply.
BUF-03電源供應的線路部份(佔PCB95%的區域),也非常適用於一般的DC+/-高品質電源供應(即BUF-03的電路部份不用)
An example for BUF03-PCB
to use in driving CT-100 phono stage amp.
