 .。在设备引脚处，不允许接地和电源平面布局紧邻信号I/O引脚。避免窄的电源和接地迹线，以小化引脚和去耦电容器之间的电感。电源连接必须始终与这些电容器断开。必须在电源引脚上使用更大（2.2µF至6.8µF）的去耦电容器，在较低频率下有效。这些设备放置在离设备更远的地方，并在PC板的同一区域中的多个设备之间共享。3.仔细选择和放置外部组件可保持OPA858的高频性能。使用低电抗电阻器。表面贴装电阻器工作得好，允许更紧凑的整体布局。切勿在高频应用中使用绕线电阻器。因为输出引脚和反相输入引脚对寄生电容敏感，所以始终将反馈和串联输出电阻器（如果有）放置在尽可能靠近输出引脚的位置。将其他网络组件（如非反相输入端接电阻器）靠近封装放置。即使低寄生电容分流外部电阻器，高电阻值也会产生显著的时间常数，从而降低性能。当将OPA858配置为电压放大器时，应将电阻值尽可能低，并与负载驱动考虑保持一致。减小电阻器值可保持电阻器 At the device pins, do not allow the ground and power plane layout to be in close proximity to the signal I/O pins. Avoid narrow power and ground traces to minimize inductance between the pins and the decoupling capacitors. The power-supply connections must always be decoupled with these capacitors. Larger (2.2-µF to 6.8-µF) decoupling capacitors, effective at lower frequency, must be used on the supply pins. These are placed further from the device and are shared among several devices in the same area of the PC board. 3. Careful selection and placement of external components preserves the high-frequency performance of the OPA858 . Use low-reactance resistors. Surface-mount resistors work best and allow a tighter overall layout. Never use wirewound resistors in a high-frequency application. Because the output pin and inverting input pin are the most sensitive to parasitic capacitance, always position the feedback and series output resistor, if any, as close to the output pin as possible. Place other network components (such as noninverting input termination resistors) close to the package. Even with a low parasitic capacitance shunting the external resistors, high resistor values create significant time constants that can degrade performance. When configuring the OPA858 as a voltage amplifier, keep resistor values as low as possible and consistent with load driving considerations. Decreasing the resistor values keeps the resistor
