The ADS1292RIRSMT 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 ADS1292RIRSMT has programmable gain settings, and optimizing them depends on the specific application and signal amplitude. A good starting point is to use the default gain settings and adjust them based on the signal amplitude and desired signal-to-noise ratio (SNR). It's also essential to consider the input impedance and the electrode characteristics.
The ADS1292RIRSMT has built-in filters, but additional filtering may be necessary to remove noise and interference. TI recommends using a combination of analog and digital filtering techniques, such as notch filters, low-pass filters, and adaptive filtering algorithms. It's also essential to use proper shielding, grounding, and layout techniques to minimize electromagnetic interference (EMI).
To ensure EMC, it's essential to follow proper design and layout practices, such as using a solid ground plane, separating analog and digital grounds, and minimizing the length of analog signal traces. Additionally, TI recommends using shielding, filtering, and surge protection devices to minimize the risk of electromagnetic interference (EMI).
The recommended power-up sequence for the ADS1292RIRSMT is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry, which helps to prevent digital noise from affecting the analog signals.
