USER’S MANUAL
Since the sample amplifier is powered by V
input signal levels up to but not exceeding V
the input signal is outside of this range, the output from the sample amplifier is clipped.
In addition, V
as V
sample amplifier has accurately transferred the input signal, resolution is ratiometric
within the limits defined by V
plifier can never transfer a full-scale value. If V
fier can never transfer a zero value.
Figure 10-5 shows the results of reference voltages outside the range defined by
V
This results in a maximum obtainable 10-bit conversion value of 3FE. At the bottom of
the signal range, V
10-bit conversion value of 3.
