ADS7952SDBT Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital traces separate. Additionally, use a low-ESR capacitor for the AVDD pin and a 0.1uF capacitor for the REF pin. Route the analog input traces away from the digital traces and avoid crossing them over the analog input pins.
  • The ADS7952SDBT has a power-on reset (POR) circuit that ensures the device is in a valid state after power-up. However, it's recommended to add an external POR circuit or a reset IC to ensure a clean power-up sequence. Additionally, add a 10kΩ pull-up resistor on the /RESET pin to ensure a valid reset state.
  • The ADS7952SDBT can use an external clock source or an internal oscillator. For a low-jitter clock source, use a crystal oscillator or a high-quality clock generator. Ensure the clock signal is routed close to the device and away from noisy digital signals. Use a series resistor and capacitor to filter the clock signal and reduce jitter.
  • The ADS7952SDBT has a programmable gain amplifier (PGA) that allows for input range optimization. Use the device's gain settings to adjust the input range to match your application's requirements. Additionally, use an external amplifier or attenuator to adjust the input signal level if necessary.
  • The ADS7952SDBT has a maximum junction temperature of 150°C. Ensure good thermal conductivity by using a thermal pad or a heat sink. Keep the device away from heat sources and ensure good airflow. Use thermal simulation tools to estimate the device's temperature and ensure reliable operation over the desired temperature range.
