Texas Instruments provides a recommended layout and routing guide in the ADS7229IRSAR Evaluation Module User's Guide (SLAU445). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
The ADS7229IRSAR has a flexible AFE that can be optimized for different applications. TI provides an AFE optimization tool (AFEOptimizer) that helps designers select the optimal AFE configuration for their specific application.
The ADS7229IRSAR can sample up to 1.5 MSPS, but the actual sampling rate depends on the system clock frequency, SPI clock frequency, and the number of channels being sampled. Refer to the datasheet for more information on sampling rate limitations.
The ADS7229IRSAR has high-speed digital outputs that require careful handling to avoid signal degradation. TI recommends using a high-speed digital buffer (e.g., SN74LVC2T45) and following proper PCB layout and routing guidelines to minimize signal reflections and crosstalk.
The ADS7229IRSAR has a typical power consumption of 35 mW at 1.5 MSPS. Power consumption can be reduced by optimizing the sampling rate, using the device's power-down modes, and minimizing the voltage supply. Refer to the datasheet for more information on power consumption and reduction techniques.
