ADA4891-2ARMZ-RL Frequently Asked Questions (FAQs)

  • A good PCB layout for the ADA4891-2 involves keeping the input and output traces short and away from each other, using a solid ground plane, and decoupling the power supplies with capacitors. A 4-layer PCB with a dedicated ground plane is recommended.
  • The gain resistors should be chosen based on the desired gain and bandwidth. A good starting point is to use 1 kΩ to 10 kΩ resistors for gains up to 10, and 100 Ω to 1 kΩ 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 ADA4891-2 is 1.3 W per amplifier, assuming a 5 V supply and a 150°C junction temperature. The power dissipation can be calculated using the formula: Pd = (Vcc x Icc) + (Vee x Iee).
  • Yes, the ADA4891-2 can be used as a single-ended amplifier by tying the inverting input to ground and applying the signal to the non-inverting input. However, this will reduce the common-mode rejection ratio and increase the noise.
  • Noise and oscillations can be filtered out using a combination of capacitors and resistors in the feedback loop. A 10 nF to 100 nF capacitor in parallel with a 100 Ω to 1 kΩ resistor can be used to filter out high-frequency noise. Additionally, a 10 μF to 100 μF capacitor can be used to decouple the power supplies.
