DAC7714UB datasheet by Texas Instruments

DAC7714UB Frequently Asked Questions (FAQs)

• What is the maximum output current of the DAC7714UB?
  The maximum output current of the DAC7714UB is 5mA per channel.
• How do I ensure monotonicity of the DAC output?
  To ensure monotonicity, use a clock frequency of at least 10 times the update rate, and ensure that the input data is properly formatted and synchronized with the clock signal.
• What is the effect of temperature on the DAC7714UB's performance?
  The DAC7714UB's performance is affected by temperature, with a typical temperature coefficient of -0.003% FSR/°C. This means that the output voltage will decrease by 0.003% of the full-scale range for every degree Celsius increase in temperature.
• How do I handle the power-on reset (POR) of the DAC7714UB?
  The DAC7714UB has a power-on reset (POR) circuit that resets the device to a known state after power-up. To handle POR, ensure that the power supply is stable and within the recommended operating range before applying a clock signal or input data.
• What is the recommended layout and routing for the DAC7714UB?
  To minimize noise and ensure proper operation, use a multi-layer PCB with a solid ground plane, and route the analog and digital signals separately. Keep the analog output traces short and away from digital signals, and use decoupling capacitors to filter the power supply.
