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.
