DAC715PB datasheet by Texas Instruments

DAC715PB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC715PB?
  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 DAC715PB?
  To ensure accurate voltage output, make sure to use a stable reference voltage, keep the analog input voltage within the specified range, and minimize noise on the analog input lines.
• What is the maximum output current of the DAC715PB?
  The maximum output current of the DAC715PB is 5mA. Exceeding this current may cause the output voltage to droop or the device to overheat.
• Can I use the DAC715PB in a ratiometric configuration?
  Yes, the DAC715PB can be used in a ratiometric configuration, where the reference voltage is derived from the power supply voltage. However, this may affect the accuracy and linearity of the output voltage.
• How do I handle the digital input signals to the DAC715PB?
  The digital input signals should be driven by a CMOS-compatible output stage, and the input voltage should be within the specified range (typically 0 to VCC). Also, ensure that the input signals are properly terminated to prevent ringing and reflections.
