DAC7621E Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
  • To ensure accurate voltage output, it is essential to use a high-quality voltage reference, such as the Texas Instruments REF5025. Additionally, ensure that the output voltage is buffered with an op-amp, such as the OPA333, to prevent loading effects.
  • The maximum output current of the DAC7621E is 5 mA. Exceeding this current may cause damage to the device or affect its accuracy.
  • To implement a bipolar output voltage range, use an external amplifier, such as the OPA333, to invert and scale the output voltage. This allows for a bipolar output voltage range, such as ±5 V or ±10 V.
  • The settling time of the DAC7621E is typically 10 μs to 1 LSB (least significant bit) accuracy. However, this may vary depending on the output voltage range and the load conditions.
