The differential output allows the DAC to drive balanced loads such as transformer-coupled RF stages or differential amplifier inputs, rejecting common-mode noise from the digital supply rails. ## Supply rails and thermal management on the PCB The device requires two analog supply ranges — 1.71 V to 1.89 V for the core and 3.15 V to 3.45 V for the output stage — plus a separate digital supply at 1.71 V to 1.89 V, so the board must route three clean supply domains with adequate decoupling at the 64-VFQFN exposed pad. ## Linearity and interface for waveform fidelity INL is ±0.5 LSB and DNL is ±0.2 LSB — the integral nonlinearity stays within half an LSB, so the output spectrum in a communications waveform generator will not show spurious tones from DAC nonlinearity at the 12-bit level. The LVDS parallel data interface transfers 12-bit words at high speed with low noise coupling into the analog output, but the layout must match the LVDS differential trace impedance (typically 100 Ω) and keep the pair lengths equal to avoid skew.","metaTitle":"TI DAC3161IRGCT 12-bit DAC, 11ns settling, 64-VQFN","metaDescription":"Texas Instruments DAC3161IRGCT 12-bit current-output DAC, 11ns typ settling, LVDS parallel interface, -40°C to 85°C, 64-VFQFN.
