音频项目中使用opamp ic LM358能否验证所附电路？

你好，先生，
对于音频信号（10nF和1kOhm => 15.9kHz和1.5nF以及330欧姆=> 322kHz），截止频率太高。
如果你想保持增益不变，你应该将10nF和1.5nF电容分别增加到至少10uF和22uF。
 最好的祝福，
P

Hi Sir,
The cutoff frequencies are too high for audio signal (10nF and 1kOhm => 15.9kHz and 1.5nF and 330 Ohm => 322kHz).
If you want to keep the gain unchanged, you should increase the 10nF and 1.5nF capacitors to respectively at least 10uF and 22uF.
  Best Regards,
P

这款双通道运算放大器利用四通道运算放大器完善的电路设计，具有低功耗，共模输入电压范围，可扩展至地/ VEE，以及单电源或分离电源供电。 LM358系列相当于LM324的一半。这些放大器与单电源应用中的标准运算放大器类型相比具有几个明显的优它们可以在低至3.0 V或高达32 V的电源电压下工作，静态电流约为MC1741的五分之一（基于每个放大器）。共模输入范围包括负电源，从而消除了许多应用中外部偏置元件的必要性。输出电压范围还包括负电源电压。的帮助

Utilizing the circuit designs perfected for quad op-amps, this dual op-amp features low power drain, a common mode input voltage range extending to ground/VEE, and single supply or split supply operation. The LM358 series is equivalent to one-half of an LM324. These amplifiers have several distinct advantages over standard operational amplifier types in single supply applications. They can operate at supply voltages as low as 3.0 V or as high as 32 V, with quiescent currents about one-fifth of those associated with the MC1741 (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage. The assistance of
