OPA2835ID Frequently Asked Questions (FAQs)

  • A good PCB layout for OPA2835ID involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated ground plane is recommended.
  • The gain resistors (Rf and Rg) should be chosen based on the desired gain and bandwidth of the amplifier. A higher gain requires smaller resistors, while a lower gain requires larger resistors. The datasheet provides a gain resistor calculator to help with the selection.
  • The maximum power dissipation of OPA2835ID is 1.4W. This is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W. The actual power dissipation will depend on the operating conditions and the PCB design.
  • Yes, OPA2835ID 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 the power supply rejection ratio (PSRR) of the amplifier.
  • OPA2835ID has a built-in filter that can be enabled by connecting a capacitor between the FLT pin and ground. The filter cutoff frequency can be adjusted by changing the value of the capacitor. Additionally, external filters can be used to further reduce noise and interference.
