OPA347UA/2K5 datasheet by Texas Instruments

OPA347UA/2K5 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of OPA347UA/2K5?
  Texas Instruments recommends a layout that minimizes parasitic capacitance and inductance, with a solid ground plane and short traces. A 4-layer PCB with a dedicated analog ground plane is recommended. See the TI application note 'AN-1187: PCB Layout for Switching Regulators' for more details.
• How do I choose the right output capacitor for OPA347UA/2K5?
  Choose an output capacitor with low ESR (Equivalent Series Resistance) and high ripple current rating. A 10uF to 22uF ceramic capacitor with X5R or X7R dielectric is recommended. See the TI application note 'SLVA883: Op Amp Output Capacitor Selection' for more details.
• What is the maximum power dissipation of OPA347UA/2K5?
  The maximum power dissipation of OPA347UA/2K5 is dependent on the ambient temperature and the thermal resistance of the package. For the 2K5 package, the maximum power dissipation is approximately 1.4W at 25°C ambient temperature. See the TI datasheet for more details.
• Can I use OPA347UA/2K5 in a high-temperature environment?
  Yes, OPA347UA/2K5 is rated for operation from -40°C to 125°C. However, the maximum junction temperature should not exceed 150°C. See the TI datasheet for more details on thermal characteristics.
• How do I protect OPA347UA/2K5 from electromagnetic interference (EMI)?
  Use a shielded enclosure, keep the PCB away from sources of EMI, and use a common-mode choke or ferrite bead on the input and output lines. See the TI application note 'SLAA092: EMI Rejection Ratio of Operational Amplifiers' for more details.
