Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Use short, direct traces for analog signals, and avoid crossing digital signals over analog signals. Also, use a common mode filter capacitor between the analog and digital grounds.
Use a high-quality, low-jitter clock source with a frequency of 10-40 MHz. Ensure the clock signal is properly terminated, and use a clock buffer if necessary. Also, ensure the clock signal is synchronized with the conversion process to minimize jitter.
Power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. Ensure the analog supply is stable before applying the clock signal.
The ADS8584SIPMR outputs 16-bit data in two's complement format. Use a FIFO or a buffer to handle the output data, and consider using a digital signal processor (DSP) or a microcontroller (MCU) to process the data. Apply digital filtering, gain correction, and offset correction as needed.
The ADS8584SIPMR has a maximum junction temperature of 150°C. Ensure good thermal conductivity between the device and the PCB, and use thermal vias if necessary. Also, consider using a heat sink or a thermal interface material to improve heat dissipation.
