DAC121C081CISD/NOPB Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VREF, and then the digital inputs. This ensures proper device operation and prevents potential latch-up conditions.
  • To ensure accurate voltage output, it is essential to use a stable and low-noise voltage reference (VREF) and to decouple the power supply lines (VCC) with suitable capacitors. Additionally, the output voltage should be buffered with an op-amp if it needs to drive a load.
  • The maximum output current of the DAC121C081 is 5mA. Exceeding this current may cause damage to the device or affect its accuracy.
  • During power-down or reset, the DAC121C081's output is high-impedance, which means it is in a high-impedance state. To prevent unwanted voltage levels, it is recommended to add a pull-down or pull-up resistor to the output pin to ensure a defined voltage level.
  • To minimize noise and ensure accurate operation, it is recommended to keep the analog and digital signal paths separate, use a solid ground plane, and keep the power supply lines (VCC) and voltage reference (VREF) as short and direct as possible.
