Texas Instruments provides a recommended layout and routing guide in the ADS5231IPAG Evaluation Module User's Guide (SLAU292). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
The ADS5231IPAG datasheet provides a general guideline for the analog input filter. However, the optimal filter design depends on the specific application's frequency range, noise environment, and signal amplitude. Engineers can use tools like the TI FilterPro software or consult with TI's application engineers to optimize the filter design.
While the datasheet specifies a maximum clock frequency of 80 MHz, the actual maximum frequency may be limited by the system's noise environment, PCB layout, and clock signal quality. It's recommended to consult with TI's application engineers or perform thorough testing to determine the maximum clock frequency for a specific design.
The ADS5231IPAG outputs 14-bit digital data in a binary two's complement format. Engineers should ensure that their digital signal processing chain can handle this data format and perform any necessary data manipulation, such as offset correction, gain adjustment, or data formatting for further processing.
The POR timing is not explicitly specified in the datasheet. However, according to TI's application engineers, the POR timing is typically around 10 ms to 20 ms. Engineers should ensure that their system design can accommodate this timing requirement to ensure proper device initialization.
