OPA4345EA/250 Frequently Asked Questions (FAQ)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common-mode filter capacitor between the input pins and a decoupling capacitor between the power supply pins and ground.

  • To ensure stability, it's recommended to use a compensation capacitor between the output and the inverting input pins. The value of the capacitor depends on the gain configuration and the desired bandwidth. A good starting point is to use a capacitor value of 10-22pF.

  • The maximum power dissipation of OPA4345EA/250 is 500mW. However, this value can be limited by the thermal resistance of the package and the PCB. It's recommended to use a heat sink or a thermal pad to ensure reliable operation.

  • Yes, OPA4345EA/250 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the power dissipation and to use a heat sink or a thermal pad to ensure reliable operation.

  • To protect OPA4345EA/250 from ESD damage, it's recommended to use ESD protection devices such as TVS diodes or ESD arrays on the input and output pins. Additionally, it's recommended to use a static-dissipative work surface and to handle the device by the body rather than the pins.
