THS3061DGN datasheet by Texas Instruments

THS3061DGN Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A good PCB layout is crucial for optimal performance. TI recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, decoupling capacitors should be placed close to the device.
• How do I choose the right gain resistors for my application?
  The gain resistors (Rf and Rg) should be chosen based on the desired gain and bandwidth. A higher gain requires smaller resistors, while a lower gain requires larger resistors. TI provides a gain resistor calculator tool to help with the selection.
• What is the maximum power dissipation of the THS3061DGN?
  The maximum power dissipation of the THS3061DGN is 1.4W. This should be taken into account when designing the thermal management of the system.
• Can I use the THS3061DGN as a single-ended amplifier?
  Yes, the THS3061DGN 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 amplifier's common-mode rejection ratio (CMRR).
• How do I filter out high-frequency noise in my application?
  The THS3061DGN has a built-in low-pass filter, but additional filtering may be required depending on the application. TI recommends using external filters, such as RC filters or ferrite beads, to filter out high-frequency noise.
