ADS7128IRTET Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The analog signals should be routed close to the ADC, and the digital signals should be routed away from the ADC. Additionally, the power and ground pins should be decoupled with 0.1uF and 10uF capacitors.
  • To optimize the performance of the ADS7128IRTET in noisy environments, use a low-pass filter at the input, use a shielded cable, and keep the ADC away from noise sources. Additionally, use a common-mode filter or a differential amplifier to reduce common-mode noise.
  • The recommended clock frequency for the ADS7128IRTET is between 1MHz to 20MHz. However, the optimal clock frequency depends on the specific application and the desired sampling rate.
  • The latency of the ADS7128IRTET is approximately 12 clock cycles. To handle the latency, use a FIFO or a buffer to store the data, or use a DMA controller to transfer the data to the processor.
  • The recommended power-up sequence for the ADS7128IRTET 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.
