Typical Applications
(Continued)
A low speed ramp generator can also be used to sweep the
analog input voltage and the LED outputs will provide a bi-
nary counting sequence from zero to full-scale.
The techniques described so far are suitable for an engi-
neering evaluation or a quick check on performance. For a
higher speed test system, or to obtain plotted data, a digital-
to-analog converter is needed for the test set-up. An accu-
rate 10-bit DAC can serve as the precision voltage source
for the A/D. Errors of the A/D under test can be provided as
either analog voltages or differences in two digital words.
A basic A/D tester which uses a DAC and provides the error
as an analog output voltage is shown in Figure 6. The 2 op
amps can be eliminated if a lab DVM with a numerical sub-
traction feature is available to directly readout the difference
voltage, ‘‘A–C’’.
For operation with a microprocessor or a computer-based
test system, it is more convenient to present the errors digi-
tally. This can be done with the circuit ofFigure 7 where the
output code transitions can be detected as the 10-bit DAC is
incremented. This provides
(/4
LSB steps for the 8-bit A/D
under test. If the results of this test are automatically plotted
with the analog input on the X axis and the error (in LSB’s)
as the Y axis, a useful transfer function of the A/D under
test results. For acceptance testing, the plot is not neces-
sary and the testing speed can be increased by establishing
internal limits on the allowed error for each code.
