DAC712PB datasheet by Texas Instruments

DAC712PB Frequently Asked Questions (FAQs)

• What is the maximum output current of the DAC712PB?
  The maximum output current of the DAC712PB is 5mA. This is not explicitly stated in the datasheet, but it can be inferred from the output impedance and voltage range specifications.
• How do I ensure monotonicity when using the DAC712PB?
  To ensure monotonicity, it is recommended to use a clock frequency of at least 10 times the update rate, and to use a settling time of at least 10us. Additionally, the output voltage should be buffered with an op-amp to prevent loading effects.
• What is the effect of temperature on the DAC712PB's performance?
  The DAC712PB's performance is affected by temperature, with a typical temperature coefficient of ±2ppm/°C for the output voltage and ±1ppm/°C for the gain error. This means that the output voltage and gain error will vary slightly with temperature, but the device remains functional over the specified operating temperature range.
• Can I use the DAC712PB in a ratiometric configuration?
  Yes, the DAC712PB can be used in a ratiometric configuration, where the output voltage is proportional to the reference voltage. This can be useful in applications where the reference voltage is derived from a power supply or other voltage source.
• How do I handle the power-on reset (POR) of the DAC712PB?
  The DAC712PB has a power-on reset (POR) circuit that resets the device to a default state when the power supply is turned on. To handle the POR, it is recommended to use a reset signal to initialize the device after power-on, and to ensure that the clock signal is stable before starting conversions.
