DAC8728SRTQT Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and routing guide in the DAC8728SRTQT datasheet (SLAS964) and the High-Speed Layout Guidelines application note (SLLA187). Key takeaways include keeping analog and digital signals separate, using a solid ground plane, and minimizing trace lengths and loops.
  • The internal voltage reference can be enabled by setting the VREF_EN pin high. However, this may introduce noise and reduce accuracy. Using an external reference can improve accuracy but requires additional components and careful layout. Consult the datasheet and the Voltage Reference Selection Guide (SLAA443) for more information.
  • The maximum update rate for the DAC8728SRTQT is 2.5 MSPS. However, the output settling time increases with higher update rates. To achieve the fastest settling time, use a lower update rate and ensure the output capacitor is properly sized. Consult the datasheet and the Settling Time and Output Capacitor Selection application note (SLAA445) for more information.
  • To implement a bipolar output configuration, use an external amplifier and resistive network to shift the output voltage. Key considerations include ensuring the amplifier's bandwidth and slew rate meet the application's requirements, and carefully selecting the resistors to maintain accuracy and minimize noise. Consult the datasheet and the Bipolar Output Configuration application note (SLAA446) for more information.
  • The DAC8728SRTQT requires a power-on reset (POR) to ensure proper initialization. The POR timing and power-up sequencing are critical to prevent incorrect device behavior. Consult the datasheet and the Power-On Reset and Power-Up Sequencing application note (SLAA447) for more information.
