12.1 Device Support
12.1.1 Device Nomenclature
12.1.1.1 Definitions of Specifications and Terminology
-
Differential Nonlinearity (DNL)Defined as the variation in analog output associated with an ideal 1 LSB change in the digital input code.
-
Gain Drift Defined as the maximum change in gain, in terms of ppm of full-scale range (FSR) per °C, from the value at 25°C to values over the full operating temperature range.
-
Gain ErrorDefined as the percentage error in the ratio between the measured full-scale output current and the value of the ideal full-scale output (32 x VREFIO / RBIAS). A VREFIO of 1.2 V is used to measure the gain error with an external reference voltage applied. With an internal reference, this error includes the deviation of VREFIO (internal bandgap reference voltage) from the typical value of 1.2 V.
-
Integral Nonlinearity (INL)Defined as the maximum deviation of the actual analog output from the ideal output, determined by a straight line drawn from zero scale to full scale.
-
Intermodulation Distortion (IMD3, IMD)The two-tone IMD3 or four-tone IMD is defined as the ratio (in dBc) of the worst third-order (or higher) intermodulation distortion product of either fundamental output tone.
-
Offset Drift Defined as the maximum change in dc offset, in terms of ppm of full-scale range (FSR) per °C, from the value at 25°C to values over the full operating temperature range.
-
Offset ErrorDefined as the percentage error in the ratio of the differential output current (IOUT_P – IOUT_N) to half of the full-scale output current for input code 8192.
-
Output Compliance RangeDefined as the minimum and maximum allowable voltage at the output of the current-output DAC. Exceeding this limit may result in reduced reliability of the device or adversely affecting distortion performance.
-
Power Supply Rejection Ratio (PSSR)Defined as the percentage error in the ratio of the delta IOUT and delta supply voltage normalized with respect to the ideal IOUT current.
-
Reference Voltage DriftDefined as the maximum change of the reference voltage in ppm per °C from the value at ambient (25°C) to values over the full operating temperature range.
-
Spurious Free Dynamic Range (SFDR)Defined as the difference (in dBc) between the peak amplitude of the output signal and the peak spurious signal.
-
Signal-to-Noise Ratio (SNR)Defined as the ratio of the RMS value of the fundamental output signal to the RMS sum of all other spectral components below the Nyquist frequency, including noise, but excluding the first six harmonics and dc.
-
Total Harmonic Distortion (THD)Defined as the ratio of the RMS sum of the first six harmonic components to the RMS value of the fundamental output signal.

12.3 Electrostatic Discharge Caution
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
