The ADS1263IPW requires careful PCB layout and placement to minimize noise and ensure optimal performance. TI recommends placing the device close to the analog signal sources, using a solid ground plane, and keeping analog and digital traces separate. Additionally, decoupling capacitors should be placed close to the device's power pins.
To optimize the ADS1263IPW's performance, consider the following: choose the correct gain setting, adjust the sampling rate, and select the appropriate filter settings. Additionally, ensure proper signal conditioning, such as filtering and amplification, to improve the signal-to-noise ratio.
Using the internal reference voltage (VREF) can simplify the design, but it may introduce noise and reduce accuracy. Using an external reference voltage can improve accuracy, but it requires additional components and careful layout. Consider the trade-offs between simplicity, accuracy, and noise performance when choosing between internal or external VREF.
The ADS1263IPW has a POR and BOR circuitry to ensure proper startup and reset. Ensure that the power supply ramps up slowly and monotonically to avoid false resets. Additionally, consider adding external reset circuitry to ensure a clean reset signal.
The ADS1263IPW has a maximum junction temperature of 150°C. Ensure good thermal design practices, such as providing adequate heat dissipation, using thermal vias, and avoiding thermal hotspots. This will help prevent overheating and ensure reliable operation.
