INTEGRATING CONVERTER
FEATURES
The output of integrating ADCs represents the integral,
or average, of an input voltage over a fixed period of
time. Compared with techniques in which the input is
sampled and held, the integrating converter averages
the effects of noise. A second important characteristic
is that time is used to quantize the answer, resulting in
extremely small non-linearity errors and no missing
output codes. The integrating converter also has very
good rejection of frequencies whose periods are an
integral multiple of the measurement period. This fea-
ture can be used to advantage in reducing line
frequency noise (Figure 5-1).
