DAC904E/2K5 datasheet by Texas Instruments

DAC904E/2K5 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC904E/2K5?
  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 DAC904E/2K5?
  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-impedance output load. Additionally, consider using a voltage buffer or op-amp to condition the output signal.
• What is the maximum output current of the DAC904E/2K5?
  The maximum output current of the DAC904E/2K5 is 5 mA. Exceeding this current limit may cause device damage or affect its performance.
• How do I handle the digital inputs of the DAC904E/2K5?
  The digital inputs of the DAC904E/2K5 are CMOS-compatible and should be driven by a logic signal with a voltage swing between GND and VCC. Avoid floating inputs, and use pull-up or pull-down resistors if necessary.
• What is the thermal impedance of the DAC904E/2K5 package?
  The thermal impedance of the DAC904E/2K5 package is typically around 30°C/W. This information is essential for thermal management and heat sink design.
