DAC6573IPW datasheet by Texas Instruments

DAC6573IPW Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC6573IPW?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures proper device operation and prevents latch-up.
• How do I ensure accurate voltage output from the DAC6573IPW?
  To ensure accurate voltage output, it is essential to use a high-precision 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 minimize output impedance and improve accuracy.
• What is the maximum output current of the DAC6573IPW?
  The maximum output current of the DAC6573IPW is 5 mA. Exceeding this current may cause damage to the device or affect its accuracy.
• How do I handle the DAC6573IPW's digital interface?
  The DAC6573IPW's digital interface is a 3-wire serial interface. Ensure that the clock frequency is within the recommended range (10 kHz to 50 MHz), and use a pull-up resistor on the SCL line to prevent bus contention.
• What is the purpose of the DAC6573IPW's internal voltage reference?
  The internal voltage reference is a 2.5V bandgap reference that can be used as a voltage reference for the DAC. However, for high-accuracy applications, it is recommended to use an external voltage reference, such as the REF5025, for better performance and stability.
