AD8228BRZ Frequently Asked Questions (FAQs)

  • The AD8228BRZ is a high-gain, high-impedance amplifier, so it's crucial to follow proper layout and placement guidelines to minimize noise and parasitic capacitance. Keep the input traces short and away from noise sources, and use a solid ground plane to reduce electromagnetic interference (EMI).
  • To optimize the gain and bandwidth of the AD8228BRZ, adjust the gain-setting resistors (Rg) and the compensation capacitor (Cc) according to the datasheet. For higher gains, use smaller Rg values, and for higher bandwidths, use smaller Cc values. However, be aware that increasing the gain can compromise the amplifier's stability.
  • The AD8228BRZ can handle input voltages up to ±10V, but it's essential to ensure that the input voltage does not exceed the power supply voltage (±Vs) to prevent damage to the amplifier.
  • To reduce noise and EMI, use proper shielding, grounding, and layout techniques. Use a solid ground plane, keep the input traces short, and avoid running digital and analog traces parallel to each other. Additionally, consider using a ferrite bead or a common-mode choke to filter out high-frequency noise.
  • Yes, the AD8228BRZ can be used as a single-ended amplifier by connecting the negative input to ground and using the positive input as the signal input. However, keep in mind that the amplifier's common-mode rejection ratio (CMRR) will be compromised in single-ended mode.
