Channel diagnostics
Over-range by bit reporting
(1)
The over-range flag will come on when the normal operating range is exceeded. The will continue to convert the analog
output up to the maximum full scale range. The flag automatically resets when within the normal operating range.
(2)
Includes offset, gain, drift, non-linearity and repeatability error terms.
(3)
Output ripple is the amount a fixed output varies with time, assuming a constant load and temperature.
(4)
Repeatability is the ability of the output to reproduce output readings when the same value is applied to it consecutively,
under the same conditions and in the same direction.
