3 EVM Performance

The DAC9881 is optimized for DC performance; total harmonic distortion (THD) is typically at -80 dB. The

EVM INL and DNL testing is performed using a high-density DAC bench test board, an Agilent 3458A

digital multimeter, and a personal computer (PC) running LabVIEW™ software. The EVM board is tested

for all codes of 262,144 × 8 bits organization and the DAC is allowed to settle for 1 ms before the meter is

read. This process is repeated for all codes to generate the measurements for INL and DNL.

Figure 8 shows the INL and DNL characteristic plots.
