The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital inputs. This ensures that the internal circuitry is properly biased and that the DAC outputs are stable.
The output voltage range of the DAC124S085CIMM is dependent on the VREF input. The output voltage range is 0 to VREF. To achieve a specific output voltage range, adjust the VREF input accordingly. For example, to get a 0 to 5V output range, set VREF to 5V.
The settling time of the DAC124S085CIMM is typically around 10-15 μs, but it can vary depending on the output load, capacitance, and the specific application. It's recommended to consult the datasheet and application notes for more information.
To reduce noise and glitches on the output of the DAC124S085CIMM, use a low-pass filter, such as an RC filter, to filter out high-frequency noise. Additionally, ensure that the digital inputs are properly synchronized and that the clock signal is clean and stable.
The maximum clock frequency that the DAC124S085CIMM can handle is 40 MHz. However, it's recommended to consult the datasheet and application notes for specific guidance on clock frequency and timing requirements.
