LM4865M/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM4865M involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing the decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
  • The gain resistors (Rf and Ri) should be chosen based on the desired gain and input impedance. A higher gain requires smaller resistors, while a higher input impedance requires larger resistors. The datasheet provides a gain resistor calculator to help with the selection.
  • The maximum power dissipation of the LM4865M is dependent on the ambient temperature and the thermal resistance of the package. The datasheet provides a power dissipation calculator to help determine the maximum power dissipation for a given application.
  • Yes, the LM4865M can be used in a single-supply configuration. However, the input common-mode range is limited to VCC-1.5V to VCC, and the output voltage swing is reduced. A voltage divider or a virtual ground circuit may be required to bias the input signals.
  • The LM4865M is a high-gain amplifier and can be susceptible to noise and EMI. To filter out noise and EMI, use a low-pass filter at the input, add a ferrite bead or a common-mode choke to the power supply lines, and use a shielded enclosure or a metal can package.
