DAC084S085CIMM/NOPB datasheet by Texas Instruments

DAC084S085CIMM/NOPB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC084S085?
  The recommended power-up sequence is to apply VCC first, followed by the digital supply (VDD), and then the analog supply (VREF). This ensures proper device operation and prevents latch-up.
• How do I ensure accurate output voltage levels from the DAC084S085?
  To ensure accurate output voltage levels, it is essential to use a stable and low-noise reference voltage (VREF) and to decouple the analog supply (VCC) and digital supply (VDD) properly. Additionally, ensure that the output load is within the recommended range.
• What is the maximum output current capability of the DAC084S085?
  The maximum output current capability of the DAC084S085 is 5 mA. Exceeding this limit may cause damage to the device or affect its performance.
• How do I handle the DAC084S085's digital interface?
  The DAC084S085 has a 3-wire serial interface. Ensure that the clock frequency is within the recommended range (10 kHz to 50 MHz), and that the data is clocked in on the rising edge of the clock signal. Also, ensure that the CS (chip select) signal is low during data transfer.
• What is the purpose of the DAC084S085's internal reference voltage (VREF) pin?
  The internal reference voltage (VREF) pin is used to set the full-scale output voltage of the DAC. It can be connected to an external reference voltage or left unconnected to use the internal 1.5 V reference voltage.
