The ADS1294IPAGR is a sensitive analog device, and proper layout and placement are crucial for optimal performance. TI recommends placing the device close to the electrodes, using a star-ground configuration, and minimizing the length of analog signal traces. Additionally, it's essential to separate analog and digital grounds and to use a solid ground plane.
The ADS1294IPAGR has programmable gain settings, and optimizing them for your specific application requires understanding the signal amplitude and frequency content. TI recommends starting with the default gain settings and adjusting them based on the signal amplitude and noise floor. It's also essential to consider the input impedance and the electrode characteristics.
The ADS1294IPAGR has built-in filters, but additional filtering may be necessary depending on the application. TI recommends using a combination of analog and digital filtering techniques, such as notch filters, low-pass filters, and adaptive filtering. It's also essential to consider the noise sources, such as electromagnetic interference (EMI) and radio-frequency interference (RFI).
The ADS1294IPAGR is a sensitive device, and ensuring EMC is crucial. TI recommends following proper PCB design practices, such as using a solid ground plane, minimizing trace lengths, and using shielding. Additionally, it's essential to consider the device's electromagnetic susceptibility and immunity to ensure reliable operation.
The ADS1294IPAGR has specific power sequencing requirements to ensure proper operation. TI recommends powering up the device in the following sequence: AVDD, DVDD, and then the clock signal. It's also essential to ensure that the power supplies are stable and well-regulated.
