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 potential latch-up conditions.
The DAC8801 has an output voltage range of 0 to VREF. To ensure accurate output voltage, the reference voltage (VREF) should be set to the desired maximum output voltage. Additionally, the output voltage should be buffered with an op-amp if it needs to drive a load.
Clock jitter can affect the DAC8801's performance by introducing noise and distortion in the output signal. To minimize the impact of clock jitter, use a high-quality clock source with low jitter, and consider using a clock jitter attenuator or a phase-locked loop (PLL) to clean up the clock signal.
To implement a bipolar output voltage range, use an op-amp to invert and scale the output voltage of the DAC8801. For example, you can use an op-amp in an inverting configuration with a gain of -1 to invert the output voltage, and then add an offset voltage to shift the output voltage range to the desired bipolar range.
The maximum output current of the DAC8801 is 5 mA. Exceeding this current limit can cause the output voltage to droop or the device to overheat. If a higher output current is required, consider using an external op-amp or buffer to boost the output current.
