LTC2268IUJ-12#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use short, wide traces for the high-frequency signals and keep the sensitive analog nodes away from the digital signals.
  • Use a low-pass filter at the input to reduce high-frequency noise. Add a ferrite bead or a common-mode choke to the power supply lines to reduce electromagnetic interference (EMI). Use a shielded enclosure and keep the analog circuitry away from the digital circuitry.
  • The maximum clock frequency is 125 MSPS. However, the actual clock frequency may be limited by the specific application and the quality of the clock signal. It's recommended to use a high-quality clock source and to follow the clocking guidelines in the datasheet.
  • Use a high-quality analog input signal with a bandwidth that is at least 2-3 times the sampling frequency. Ensure that the analog input signal is properly filtered and amplified before being applied to the ADC. Use the built-in error correction features of the LTC2268IUJ-12, such as the cyclic redundancy check (CRC) and the error detection and correction (EDC) features.
  • The power consumption of the LTC2268IUJ-12 is typically around 1.2W. To reduce power consumption, use the power-down mode when the ADC is not in use. Reduce the clock frequency to the minimum required for the application. Use a low-power mode of operation, such as the 'Nap' mode, when the ADC is idle.
