The recommended power-up sequence is to apply VCC first, followed by VDD, and then the analog power supplies (VAA and VBB). This ensures that the internal voltage regulators are powered up correctly.
To optimize ADC performance, ensure that the analog input signal is within the recommended range, use a low-pass filter to remove high-frequency noise, and adjust the ADC clock frequency to minimize jitter. Additionally, consider using the internal ADC calibration feature to improve accuracy.
The maximum allowed capacitance on the analog input pins is 10 nF. Exceeding this value can affect the ADC's performance and accuracy.
To handle clock jitter and skew, use a high-quality clock source, ensure that the clock signals are properly terminated, and consider using a clock jitter attenuator or a phase-locked loop (PLL) to synchronize the clocks.
To minimize noise and interference, use a multi-layer PCB with separate analog and digital ground planes, keep analog and digital signals separate, and use shielding and guard rings around sensitive signals. Additionally, follow the recommended pinout and layout guidelines in the datasheet.
