Notes:
General Note: Typical values represent the mean value of all char-
acterization units at the nominal operating conditions. Typical drift
specifications are determined by calculating the rate of change of the
specified parameter versus the drift parameter (at nominal operating
conditions) for each characterization unit, and then averaging the indi-
vidual unit rates. The corresponding drift figures are normalized to the
nominal operating conditions and show how much drift occurs as the
particular drift parameter is varied from its nominal value, with all other
parameters held at their nominal operating values. Note that the typical
drift specifications in the tables may differ from the slopes of the mean
curves shown in the corresponding figures.

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 attenuated 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.
