DAC7631EB/1K datasheet by Texas Instruments

DAC7631EB/1K Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC7631?
  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 potential latch-up conditions.
• How do I ensure accurate voltage output from the DAC7631?
  To ensure accurate voltage output, it's essential to use a high-precision voltage reference, such as the REF5025, and to follow proper PCB layout and grounding techniques to minimize noise and interference.
• What is the maximum output current of the DAC7631?
  The maximum output current of the DAC7631 is 5mA. Exceeding this current limit can cause damage to the device or affect its accuracy.
• Can I use the DAC7631 with a single supply voltage?
  Yes, the DAC7631 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-1.4V.
• How do I handle the DAC7631's power-down mode?
  When the DAC7631 is in power-down mode, the output voltage is undefined. To ensure a safe shutdown, it's recommended to disconnect the load from the output pin or use an external buffer amplifier to maintain a stable output voltage.
