ADA4891-4ARUZ-RL Frequently Asked Questions (FAQs)

  • A good PCB layout for the ADA4891-4 involves keeping the input and output traces short and away from each other, using a solid ground plane, and decoupling the power supplies with 0.1uF and 10uF capacitors. A 4-layer PCB with a dedicated analog ground plane is also recommended.
  • The gain resistors for the ADA4891-4 should be chosen based on the desired gain and bandwidth. A good starting point is to use 1kΩ to 10kΩ resistors for gains up to 10, and 100Ω to 1kΩ resistors for gains above 10. The resistors should also be matched to within 0.1% to ensure good common-mode rejection.
  • The maximum power dissipation for the ADA4891-4 is 1.3W per amplifier, assuming a 5V supply and a 150°C junction temperature. However, this can be derated based on the ambient temperature and the thermal resistance of the package.
  • Yes, the ADA4891-4 can be used as a single-ended to differential converter by configuring it as a differential amplifier with a gain of 1. This is useful for converting single-ended signals to differential signals for transmission over long cables or for driving differential inputs.
  • Noise and interference in the ADA4891-4 circuit can be filtered out using a combination of passive and active filters. A simple RC filter can be used to filter out high-frequency noise, while a more complex active filter can be used to filter out specific frequency bands.
