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 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 function of input. All versions of the AD667 are monotonic over their full operating temperature range. DIFFERENTIAL NONLINEARITY Monotonic behavior requires that the differential linearity error be less than 1 LSB both at +25°C and over the temperature range of interest. Differential 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 output, a change of 1 LSB in digital input code should result in a mV change in the analog output 1 LSB = 10 V x 1/4096 = mV . If in actual use, however, a 1 LSB change in the input code results in a change of only mV 1/4 LSB in analog output, the differential linearity error would be mV, or 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 1/2 LSB.
