OPA2835IRMCR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the OPA2835 application note (SLVAU93). It suggests using a symmetrical layout, keeping the input and output traces short, and using a solid ground plane to minimize noise and electromagnetic interference (EMI).
  • The gain resistors (Rf and Rg) should be chosen based on the desired gain and bandwidth. A higher gain requires smaller resistors, but may also increase noise and reduce stability. TI provides a gain resistor calculator tool (OPA2835 Gain Resistor Calculator) to help with the selection.
  • The maximum power dissipation of the OPA2835 is dependent on the ambient temperature and the package type. For the OPA2835IRMCR, the maximum power dissipation is 1.4W at 25°C ambient temperature. However, it's recommended to derate the power dissipation based on the operating temperature and to ensure a safe operating margin.
  • Yes, the OPA2835 can be used as a single-ended amplifier by tying the negative input to ground and using the positive input as the signal input. However, this will reduce the common-mode rejection ratio (CMRR) and may increase noise and distortion.
  • The OPA2835 has a built-in filter capacitor (Cf) that can be used to filter out high-frequency noise. Additionally, external filters such as RC filters or ferrite beads can be used to further reduce noise and EMI. TI provides guidance on filtering and noise reduction in the OPA2835 application note (SLVAU93).
