DAC161S997RGHR Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital inputs. This ensures proper device operation and prevents latch-up.
  • 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 with 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 DAC161S997RGHR is 5 mA. Exceeding this current may cause the output voltage to droop or the device to overheat.
  • The digital inputs of the DAC161S997RGHR are CMOS-compatible and should be driven with a logic signal that meets the VIH and VIL specifications. It is recommended to use a series resistor to limit the input current and prevent damage to the device.
  • The thermal impedance of the DAC161S997RGHR package (RHR package) is approximately 45°C/W. This value can be used to estimate the junction temperature of the device under different operating conditions.
