The recommended power-up sequence is to apply VDD first, followed by AVDD, and then the digital supply (DVDD). This ensures proper device operation and prevents potential latch-up conditions.
The DAC7625U/1K has a rail-to-rail output stage, but it's recommended to limit the output voltage range to within 100 mV of the supply rails (VDD and AVDD) to ensure optimal linearity and accuracy.
Clock jitter can affect the DAC7625U/1K's performance by introducing noise and distortion in the output signal. It's recommended to use a low-jitter clock source and to keep the clock signal path as short as possible to minimize jitter effects.
Yes, the DAC7625U/1K can be used in a multiplexed configuration, but it's essential to ensure that the output is properly settled before switching to a new channel. The settling time depends on the output load and the desired accuracy.
The DAC7625U/1K has a maximum junction temperature of 150°C. Ensure proper heat sinking and thermal management to prevent overheating, especially in high-power or high-frequency applications.
