Functional description The 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 cascode source configuration enables to increase 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 x V GAPOUT R I = ----------------------------------------- 82 x 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.

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 -- Two-tone InterModulation Distortion rejection; Second order. 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 -- Two-tone InterModulation Distortion rejection; Third order. 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. SFDR -- Spurious-Free Dynamic Range. The ratio between the RMS value of the reconstructed output sine wave and the RMS value of the largest spurious observed (harmonic and non-harmonic, excluding DC component) in the frequency domain. 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. TDA9935_4 (c) NXP B.V. 2007.
