The differential nonlinearity (DNL), sometimes referred to as differential error, is the difference between the measured and ideal 1 LSB amplitude change of any two adjacent codes. Monotonic means the output voltage changes in the same direction (or remains constant) as a change in the digital input code. Zero-scale error is defined as the deviation of the output from 0 V at a digital input value of 0. Gain error is the error in slope of the DAC transfer function. S/N+D is the ratio of the rms value of the output signal to the rms sum of all other spectral components below the Nyquist frequency, including harmonics but excluding dc. The value for S/N+D is expressed in decibels. SFDR is the difference between the rms value of the output signal and the rms value of the largest spurious signal within a specified bandwidth. The value for SFDR is expressed in decibels. THD is the ratio of the rms sum of the first six harmonic components to the rms value of the fundamental signal and is expressed in decibels. 10 |
