ADS7952SBDBT 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 keep them as short as possible.
  • The ADS7952SBDBT 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 reset circuit to ensure the device is in a valid state. A 10kΩ pull-up resistor on the RESET pin to AVDD and a 0.1uF capacitor from RESET to GND can be used.
  • The ADS7952SBDBT can use an external clock source or its internal oscillator. For an external clock source, use a low-jitter clock oscillator with a frequency of 10MHz to 50MHz. To minimize clock jitter, use a clock source with a jitter of less than 100ps and ensure the clock signal is routed away from noisy digital signals.
  • The ADS7952SBDBT has a programmable gain amplifier (PGA) that can be configured for different gain settings. To optimize the analog input range and gain, use the device's PGA to adjust the gain to match the input signal amplitude. Additionally, use the device's input multiplexer to select the correct input range for the application.
  • The ADS7952SBDBT has a SYNC pin that can be used to synchronize conversions with an external trigger signal. To use the SYNC pin, connect the external trigger signal to the SYNC pin and configure the device to use the SYNC pin as the conversion trigger. Ensure the trigger signal is synchronized with the device's clock signal.
