ADS7950SBRGET datasheet by Texas Instruments

ADS7950SBRGET Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the ADS7950SBRGET?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The datasheet provides a recommended layout and routing guide.
• How do I optimize the performance of the ADS7950SBRGET in noisy environments?
  To optimize performance in noisy environments, use a low-pass filter at the input, keep the analog and digital grounds separate, and use a shielded cable for the analog input. Additionally, consider using a common-mode filter or a ferrite bead to reduce noise.
• What is the maximum sampling rate I can achieve with the ADS7950SBRGET?
  The maximum sampling rate of the ADS7950SBRGET is 1.5 MSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and digital output data rate.
• How do I calibrate the ADS7950SBRGET for optimal performance?
  Calibration involves adjusting the offset and gain of the ADC. The datasheet provides a calibration procedure, which involves applying a known input voltage and adjusting the offset and gain registers to achieve optimal performance.
• What is the power consumption of the ADS7950SBRGET, and how can I reduce it?
  The power consumption of the ADS7950SBRGET is typically 35 mW at 1.5 MSPS. To reduce power consumption, consider using the power-down mode, reducing the sampling rate, or using a lower supply voltage.
