ADS1245IDGST datasheet by Texas Instruments

ADS1245IDGST Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the ADS1245IDGST?
  Texas Instruments provides a layout guide and PCB design checklist in the ADS1245IDGST datasheet and application notes. It's essential to follow these guidelines to ensure optimal performance, minimize noise, and reduce electromagnetic interference (EMI).
• How do I optimize the gain and offset calibration for my specific application?
  The ADS1245IDGST has a built-in calibration mechanism, but you may need to fine-tune the gain and offset calibration for your specific application. TI provides an application note (SLAA454) that explains the calibration process and provides examples of how to optimize the calibration for different scenarios.
• What is the maximum sampling rate I can achieve with the ADS1245IDGST?
  The ADS1245IDGST has a maximum sampling rate of 2000 samples per second (SPS) for a single channel, and 1000 SPS for multiple channels. However, the actual sampling rate may be limited by the system's clock frequency, filter settings, and other factors. Consult the datasheet and application notes for more information.
• How do I handle the high impedance of the ADS1245IDGST's analog inputs?
  The ADS1245IDGST has high-impedance analog inputs, which can be sensitive to noise and interference. To minimize these effects, use a low-impedance signal source, add a buffer amplifier or op-amp, and ensure proper shielding and grounding of the PCB.
• What is the power consumption of the ADS1245IDGST, and how can I reduce it?
  The ADS1245IDGST has a typical power consumption of 12.5 mW at 2.7 V and 1.5 mW at 1.8 V. To reduce power consumption, consider using the device's power-down mode, reducing the clock frequency, and optimizing the system's power management.
