Notes:
General Note: Typical values represent the mean value of all characteriza-
tion units at the nominal operating conditions. Typical drift specifica-
tions are determined by calculating the rate of change of the specified
parameter versus the drift pa-rameter (at nominal operating conditions)
for each characterization unit, and then averaging the individual unit
rates. The corresponding drift figures are normalized to the nominal
operating conditions and show how much drift occurs as the par-ticular
drift parameter is varied from its nominal value, with all other param-
eters held at their nominal operating values. Note that the typical drift
specifications in the tables below may differ from the slopes of the mean
curves shown in the corresponding figures.

and sigma-delta quantization noise. Chopper noise results from
chopper stabilization of the output op-amps. It occurs at a specific
frequency (typically 400 kHz at room temperature), and is not at-
tenuated by the internal output filter. A filter circuit can be easily
added to the external post-amplifier to reduce the total rms output
noise. The internal output filter does eliminate most, but not
all, of the sigma-delta quantization noise. The magnitude of the
output quantization noise is very small at lower frequencies (below
10 kHz) and increases with increasing frequency.
