Texas Instruments provides a recommended layout and routing guide in the ADS1672IPAGG4 Evaluation Module User's Guide (SLAU521). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
The ADS1672IPAGG4 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 TI's FilterPro or online filter design calculators to optimize the filter for their specific use case.
Clock jitter can affect the ADC's performance, particularly in high-frequency applications. The ADS1672IPAGG4 datasheet specifies a maximum clock jitter of 100 ps RMS. Engineers should ensure that their clock source meets this requirement to maintain optimal performance. Additionally, using a clock jitter cleaner or a high-quality clock source can help minimize the impact of clock jitter.
The ADS1672IPAGG4 outputs 16-bit digital data in a specific format. Engineers should consult the datasheet for the output data format and timing diagrams. They can also use TI's ADC data capture tools, such as the TSW14J56, to simplify data capture and analysis.
The ADS1672IPAGG4 has a power-down mode that reduces power consumption when the device is not in use. Engineers can use the PDWN pin to control the power-down mode. When PDWN is low, the device enters power-down mode, and when PDWN is high, the device returns to normal operation. This feature can be useful in battery-powered applications or systems with limited power budgets.
