DAC084S085CIMM datasheet by Texas Instruments

DAC084S085CIMM Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC084S085CIMM?
  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 DAC084S085CIMM?
  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 reduce the output impedance.
• What is the maximum clock frequency that the DAC084S085CIMM can handle?
  The maximum clock frequency that the DAC084S085CIMM can handle is 40 MHz. Exceeding this frequency may result in incorrect data conversion or device malfunction.
• How do I handle the DAC084S085CIMM's output during power-down or reset?
  During power-down or reset, the DAC084S085CIMM's output may go to an undefined state. To prevent this, use an external buffer amplifier or a voltage follower to hold the output voltage stable until the device is fully powered up or reset.
• What is the recommended layout and routing for the DAC084S085CIMM?
  To minimize noise and ensure proper device operation, it is recommended to keep analog and digital signal traces separate, use a solid ground plane, and place decoupling capacitors close to the device's power pins.
