OPA373AIDBVTG4 datasheet by Texas Instruments

OPA373AIDBVTG4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of OPA373AIDBVTG4?
  Texas Instruments recommends a layout that minimizes parasitic inductance and capacitance, keeps the input and output traces short and separate, and uses a solid ground plane to reduce noise and electromagnetic interference (EMI).
• How do I ensure stability and prevent oscillations in my OPA373AIDBVTG4-based circuit?
  To ensure stability, use a compensation capacitor (Cc) between the output and the inverting input, and ensure that the gain and phase margins are sufficient. Also, avoid using long input traces and keep the feedback network impedance low.
• What is the maximum power dissipation of OPA373AIDBVTG4, and how do I calculate it?
  The maximum power dissipation of OPA373AIDBVTG4 is 750mW. To calculate it, use the formula: Pd = (Vcc x Icc) + (Vout x Iout), where Vcc is the supply voltage, Icc is the quiescent current, Vout is the output voltage, and Iout is the output current.
• Can I use OPA373AIDBVTG4 in a high-temperature environment, and what are the limitations?
  Yes, OPA373AIDBVTG4 can operate in high-temperature environments, but its performance may degrade. The device is specified for operation up to 125°C, but the maximum junction temperature (Tj) should not exceed 150°C. Above 125°C, the device's accuracy, noise, and distortion may increase.
• How do I protect OPA373AIDBVTG4 from electromagnetic interference (EMI) and radio-frequency interference (RFI)?
  To protect OPA373AIDBVTG4 from EMI and RFI, use a shielded enclosure, keep the device away from sources of interference, use a common-mode choke or ferrite bead on the input and output lines, and ensure good grounding and decoupling of the power supply.
