ADS8028IRTJT Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and routing guide in the ADS8028 application note (SLAA532). It's essential to follow these guidelines to ensure optimal performance and minimize noise coupling.
  • The ADS8028IRTJT has a programmable analog input filter. To optimize the filter, you need to consider the signal frequency, noise bandwidth, and desired attenuation. TI provides a filter design tool (ADS8028 Filter Design Tool) to help you determine the optimal filter coefficients for your application.
  • The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry, which helps to prevent latch-up and ensures proper device operation.
  • The CLKIN input should be driven by a low-jitter clock source with a frequency between 10 MHz and 50 MHz. The clock signal should be a square wave with a 50% duty cycle. It's recommended to use a clock buffer or a dedicated clock source to ensure a clean and stable clock signal.
  • The maximum throughput of the ADS8028IRTJT is 1 MSPS. To optimize the throughput, ensure that the analog input signal is within the specified range, and the clock frequency is set to the maximum recommended value (50 MHz). Additionally, optimize the digital interface by using a fast SPI interface and minimizing the number of dummy cycles.
