    DAC7621EB/1K Frequently Asked Questions (FAQs)

    • The recommended power-up sequence is to apply VDD first, followed by AVDD, and then the digital supply (VCC). This ensures that the internal analog and digital circuits are properly initialized.
    • The DAC7621 has a rail-to-rail output stage, but it's not guaranteed to swing all the way to the supply rails. To ensure maximum output voltage range, use an external op-amp to buffer the output and provide additional gain if needed.
    • The maximum clock frequency for the DAC7621 is 40 MHz, but it's recommended to operate at 20 MHz or lower to ensure reliable data transfer and minimize digital noise.
    • To implement a bipolar output voltage range, use an external op-amp to invert and scale the output voltage. You can also use a voltage reference (e.g., REF5025) to generate a negative voltage rail.
    • The settling time of the DAC7621 is typically around 3-5 μs, but it can vary depending on the output voltage range, load capacitance, and other factors. Consult the datasheet and application notes for more information.
