§
Response time to
output enable (OE)
Nonlinearity is defined as the deviation of f
O
from a straight line between zero and full scale, expressed as a percent of full scale.
#
Nonlinearity test condition: S0 = S1 = H, S2 = S3 = L.
§
Principal frequency is the internal oscillator frequency, equivalent to divide-by-1 output selection.
