ADS1293CISQE/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to route the analog and digital signals separately to minimize noise and interference. A dedicated analog ground plane is also recommended.
  • Optimizing the ADC's performance requires careful selection of the gain, sampling rate, and filter settings. TI provides an ADC Performance Calculator tool to help with this process. Additionally, the ADS1293's datasheet provides guidelines for optimizing performance for different applications.
  • The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures that the ADC is properly initialized and configured before starting conversions.
  • The ADS1293's analog inputs are high-impedance, so it's essential to use a buffer amplifier or an impedance-matching network to ensure proper signal transmission and minimize signal attenuation.
  • The maximum cable length for the ADS1293's analog input signals depends on the signal frequency and amplitude. As a general rule, keep the cable length as short as possible (less than 10 inches) to minimize signal degradation and noise pickup.
