The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures proper device operation and prevents damage.
To optimize the PCB layout, keep analog and digital signals separate, use a solid ground plane, and place decoupling capacitors close to the device. Also, ensure that the analog input traces are short and direct to minimize noise pickup.
The maximum allowed input voltage is 2.5Vpp differential, exceeding which may cause distortion or damage to the device.
To minimize clock jitter, use a high-quality clock source, and consider using a clock jitter attenuator or a phase-locked loop (PLL) to reduce jitter.
The recommended operating temperature range is -40°C to 85°C. Operating outside this range may affect device performance or reliability.
