DAC5573IPWR datasheet by Texas Instruments

DAC5573IPWR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC5573IPWR?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
• How do I ensure accurate voltage output from the DAC5573IPWR?
  To ensure accurate voltage output, it is essential to use a stable reference voltage, minimize noise on the analog input pins, and use a low-noise power supply. Additionally, consider using a voltage reference buffer amplifier to improve output accuracy.
• What is the maximum output current capability of the DAC5573IPWR?
  The maximum output current capability of the DAC5573IPWR is 5 mA. Exceeding this limit may cause device damage or affect output accuracy.
• How do I handle the DAC5573IPWR's digital inputs during power-up and power-down?
  During power-up and power-down, it is recommended to keep the digital inputs in a high-impedance state or tie them to a valid logic level to prevent unwanted device behavior.
• What is the recommended layout and routing for the DAC5573IPWR?
  To minimize noise and ensure proper device operation, it is recommended to use a star-ground topology, keep analog and digital traces separate, and use a solid ground plane. Additionally, place the DAC5573IPWR close to the analog signal sources and use short, direct traces to minimize noise pickup.
