7. Functional description
The Digital-to-Analog Converter (DAC) is a segmented architecture composed of a 7-bit
thermometer sub-DAC and the remaining 7-bit in a binary weighted sub-DAC.
The device produces two complementary current outputs on both channels, respectively
pins IOUT/IOUTN and QOUT/QOUTN which need to be connected via a load resistor to
the ground.
Figure 3 shows the equivalent analog output circuit of one DAC, which consists of a
parallel combination of PMOS current sources and associated switches for each segment.
The cascade source configuration enables the increasing of the output impedance of the
source and set to improve the dynamic performance of the DAC by introducing less
distortion.
Figure 4 shows the internal reference configuration. In this case the bias current is given
by the output of the internal regulator connected to the inverting input of the internal
operational amplifiers, while external resistors RI and RQ are connected respectively to
pins IVIRES and QVIRES. Thus the output current of the two DACs is typically fixed to
20 mA with an appropriate choice of these resistors. This configuration is optimal for
temperature drift compensation because the band gap can be matched with the voltage
on the feedback resistors.
The relation between full-scale output current IO(fs) and the RI (RQ) is:
2048 × V GAPOUT
R I = ------------------------------------------ Ω
82 × I O ( fs )
The output current can also be adjusted by imposing an external reference voltage to the
inverting input pin GAPOUT and disabling the internal band gap with pin GAPD set to
HIGH. At a voltage lower than 1.2 V the current can be set at values lower than 20 mA.
The input references at pins IVIRES and QVIRES may also be driven by separate
reference voltages to adjust independently the two DAC currents.

14. Glossary
14.1 Static parameters
DNL — Differential Non-Linearity. The difference between the ideal and the measured
output value between successive DAC codes.
INL — Integral Non-Linearity. The deviation of the transfer function from a best-fit straight
line (linear regression computation).
14.2 Dynamic parameters
IMD2 — Second-order intermodulation distortion. From a dual-tone digital input sine wave
(these two frequencies are close together), the intermodulation distortion product IMD2 is
the ratio of the RMS value of either tone and the RMS value of the worst 2nd-order
intermodulation product.
IMD3 — Third-order intermodulation distortion. From a dual-tone digital input sine wave
(these two frequencies are close together), the intermodulation distortion product IMD3 is
the ratio of the RMS value of either tone and the RMS value of the worst 3rd-order
intermodulation product.
S/N — Signal-to-Noise ratio. The ratio of the RMS value of the reconstructed output sine
wave to the RMS value of the noise excluding the harmonics and the DC component.
THD — Total Harmonic Distortion. The ratio of the RMS value of the harmonics of the
output frequency to the RMS value of the output sine wave. Usually, the calculation of
THD is done on the first 5 harmonics.
SFDR — Spurious-Free Dynamic Range. The ratio of the RMS value of the reconstructed
output sine wave and the RMS value of the largest spurious (harmonic and non-harmonic,
excluding DC component) observed in the frequency domain.
