DAC081S101CIMMX/NOPB Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the DAC081S101?
  The recommended power-on sequence is to apply VDD first, followed by VREF, and then the digital inputs. This ensures proper device operation and prevents potential latch-up or damage.
• How do I ensure accurate output voltage from the DAC081S101?
  To ensure accurate output voltage, make sure to use a stable and noise-free reference voltage (VREF), and decouple the power supply (VDD) with a 0.1uF capacitor. Additionally, use a low-noise, low-impedance output load, and consider using an output filter capacitor to reduce noise and ringing.
• What is the maximum output current of the DAC081S101?
  The maximum output current of the DAC081S101 is 5mA. Exceeding this current may cause the output voltage to droop or the device to overheat.
• Can I use the DAC081S101 with a single power supply?
  Yes, the DAC081S101 can be used with a single power supply (VDD) as long as the reference voltage (VREF) is derived from the same power supply. However, using a separate reference voltage can provide better performance and accuracy.
• How do I handle the output glitch during power-on or power-off of the DAC081S101?
  To minimize output glitches during power-on or power-off, use a power-on reset (POR) circuit to ensure the digital inputs are in a known state before the DAC is enabled. Additionally, consider using a glitch filter or a soft-start circuit to reduce the output voltage transient.
