LINEARITY ERROR: Analog Devices defines linearity error as
the maximum deviation of the actual, adjusted DAC output
from the ideal analog output (a straight line drawn from 0 to
F.S. – 1 LSB) for any bit combination. This is also referred to as
relative accuracy. The AD767 is laser trimmed to typically
maintain linearity errors at less than ± 1/8 LSB for the K and B
versions and ± 1/2 LSB for the J, A and S versions. Linearity
over temperature is also held to ± 1/2 LSB (K/B) or ± 1 LSB
(J/A/S).
MONOTONICITY: A DAC is said to be monotonic if the
output either increases or remains constant for increasing digital
inputs such that the output will always be a nondecreasing
function of input. All versions of the AD767 are monotonic over
their full operating temperature range.
