Figure 4-7 shows the D/A converter with an LED circuit added. The LED circuit is the
"load" that the D/A converter must "drive". Run a voltage sweep on this circuit, and fill
in the table below. Then try the voltage sweep using the output of the voltage follower in
as shown in Figure 4-8. Fill out the same table of voltage sweep information for this
second circuit, and compare the two. The voltage follower in Figure 4-7 is referred to as a
buffer. The LED circuit has no voltage follower to separate it from the resistive ladder
network. The LED is an "unbuffered" load for the D/A converter.
