OPA2835IRUNT Frequently Asked Questions (FAQs)

  • A good PCB layout for OPA2835 involves keeping the input and output traces short and symmetrical, 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 choice of gain resistors depends on the desired gain, bandwidth, and noise requirements. A good starting point is to use the gain resistor calculator tool provided by Texas Instruments or to consult the application notes for guidance.
  • The maximum power dissipation of OPA2835 is 1.4W. However, this can be limited by the thermal resistance of the package and the PCB. It's essential to ensure proper thermal management to prevent overheating.
  • Yes, OPA2835 can be used as a single-ended amplifier. However, this will reduce the common-mode rejection ratio (CMRR) and increase the noise. It's recommended to use the device in a differential configuration for optimal performance.
  • OPA2835 has a built-in filter that can be enabled by connecting a capacitor between the FLT pin and ground. The value of the capacitor determines the filter cutoff frequency. Additionally, external filters can be used to further reduce noise.
