PGA870IRHDT 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 a star topology for the power supply and keep the power traces away from the analog signals.
  • The gain setting depends on the input signal amplitude and the desired output signal amplitude. Use the PGA870IRHDT's gain setting formula (Gain = 20 * log10(Vout/Vin)) to determine the optimal gain setting for your application. You can also use the device's internal gain calibration feature to optimize the gain setting.
  • The recommended input impedance is 1 kΩ to 10 kΩ. This ensures that the input signal is not attenuated and the PGA870IRHDT can provide the maximum gain. You can use an external resistor to match the input impedance to the source impedance.
  • Use a low-noise power supply, decouple the power supply lines, and use a ground plane to reduce noise. Keep the analog and digital signals separate and use shielding to reduce electromagnetic interference (EMI). Use a low-pass filter to remove high-frequency noise and distortion.
  • The maximum input signal amplitude is ±10 V. Exceeding this limit can cause distortion and damage to the device. Use an external attenuator or amplifier to adjust the input signal amplitude if necessary.
