DAC813JU/1K datasheet by Texas Instruments

DAC813JU/1K Frequently Asked Questions (FAQs)

• What is the recommended output buffer configuration for the DAC813JU/1K?
  The recommended output buffer configuration is a 100 ohm resistor in series with a 10nF capacitor to GND. This helps to filter out high-frequency noise and improve the overall signal-to-noise ratio.
• How do I ensure accurate voltage output from the DAC813JU/1K?
  To ensure accurate voltage output, make sure to use a high-precision voltage reference (VREF) and maintain a stable power supply. Additionally, consider using a voltage buffer amplifier, such as the OPA333, to further improve output accuracy.
• What is the maximum update rate for the DAC813JU/1K?
  The maximum update rate for the DAC813JU/1K is 1 MSPS (million samples per second). However, this rate may vary depending on the specific application, clock frequency, and output configuration.
• Can I use the DAC813JU/1K with a single-supply voltage?
  Yes, the DAC813JU/1K can operate with a single-supply voltage between 2.7V and 5.5V. However, the output voltage range will be limited to 0V to VCC, and the device's performance may be affected at lower supply voltages.
• How do I handle the DAC813JU/1K's power-on reset (POR) and brown-out reset (BOR) features?
  The DAC813JU/1K has a built-in POR and BOR feature that resets the device during power-up or brown-out conditions. To handle these features, ensure that your system design includes a proper power-up sequence and voltage monitoring circuitry to prevent unwanted resets.
