20 / 36 page AD5421 Data Sheet Rev. F | Page 20 of 36 TERMINOLOGY Total Unadjusted Error Total unadjusted error (TUE) is a measure of the total output error. TUE consists of INL error, offset error, gain error, and output drift over temperature, in the case of maximum TUE. TUE is expressed in % FSR. Relative Accuracy or Integral Nonlinearity (INL) Error Relative accuracy, or integral nonlinearity (INL) error, is a measure of the maximum deviation in the output current from a straight line passing through the endpoints of the transfer function. INL error is expressed in % FSR. Differential Nonlinearity (DNL) Error Differential nonlinearity (DNL) error is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of ±1 LSB maximum ensures monotonicity. Offset Error Offset error is a measure of the output error when zero code is loaded to the DAC register and is expressed in % FSR. Offset Error Temperature Coefficient (TC) Offset error TC is a measure of the change in offset error with changes in temperature and is expressed in ppm FSR/°C. Gain Error Gain error is a measure of the span error of the DAC. It is the deviation in slope of the DAC transfer function from the ideal and is expressed in % FSR. Gain Error Temperature Coefficient (TC) Gain error TC is a measure of the change in gain error with changes in temperature and is expressed in ppm FSR/°C. Full-Scale Error Full-scale error is a measure of the output error when full-scale code is loaded to the DAC register and is expressed in % FSR. Full-Scale Error Temperature Coefficient (TC) Full-scale error TC is a measure of the change in full-scale error with changes in temperature and is expressed in ppm FSR/°C. Loop Compliance Voltage Headroom Loop compliance voltage headroom is the minimum voltage between the LOOP− and REGIN pins for which the output current is equal to the programmed value. Output Temperature Coefficient (TC) Output TC is a measure of the change in the output current at 12 mA with changes in temperature and is expressed in ppm FSR/°C. Voltage Reference Thermal Hysteresis Voltage reference thermal hysteresis is the difference in output voltage measured at +25°C compared to the output voltage measured at +25°C after cycling the temperature from +25°C to −40°C to +105°C and back to +25°C. The hysteresis is specified for the first and second temperature cycles and is expressed in mV. Voltage Reference Temperature Coefficient (TC) Voltage reference TC is a measure of the change in the reference output voltage with a change in temperature. The voltage refer- ence TC is calculated using the box method, which defines the TC as the maximum change in the reference output voltage over a given temperature range. Voltage reference TC is expressed in ppm/°C as follows: 6 10 Temp_Range V V V TC REF_NOM REF_MIN REF_MAX where: VREF_MAX is the maximum reference output voltage measured over the total temperature range. VREF_MIN is the minimum reference output voltage measured over the total temperature range. VREF_NOM is the nominal reference output voltage, 2.5 V. Temp_Range is the specified temperature range (−40°C to +105°C). |
