THE AD667 OFFERS TRUE 12-BIT PERFORMANCE
OVER THE FULL TEMPERATURE RANGE
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 FS
– 1 LSB) for any bit combination. The AD667 is laser trimmed
to 1/4 LSB (0.006% of FS) maximum error at +25
°
C for the K
and B versions and 1/2 LSB for the J, A and S versions.
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 func-
tion of input. All versions of the AD667 are monotonic over
their full operating temperature range.
DIFFERENTIAL NONLINEARITY: Monotonic behavior re-
quires that the differential linearity error be less than 1 LSB
both at +25
°
C and over the temperature range of interest. Dif-
ferential nonlinearity is the measure of the variation in analog
value, normalized to full scale, associated with a 1 LSB change
in digital input code. For example, for a 10 volt full-scale out-
put, a change of 1 LSB in digital input code should result in a
2.44 mV change in the analog output (1 LSB = 10 V
×
1/4096 =
2.44 mV). If in actual use, however, a 1 LSB change in the
input code results in a change of only 0.61 mV (1/4 LSB) in
analog output, the differential linearity error would be –1.83 mV,
or –3/4 LSB. The AD667K and B grades have a max differential
linearity error of 1/2 LSB, which specifies that every step will be
at least 1/2 LSB and at most 1 1/2 LSB.
