【选型】如何为音频放大电路选择一款合适的模拟运算放大器?
音频放大电路由前置电压放大级、音调控制级、功率放大级等三部分组成,其中前置电压放大级主要负责前置电压信号的放大;音调控制级主要负责音调的调节;而功率放大级主要负责对音调控制级输出的电流信号放大,然后驱动喇叭工作,而设计成功的关键还在于模拟运放的合理选型。
下面以麦克风电压采集放大电路为例,说明下模拟运放选型注意事项,参考电路如下图1所示,其中MIC输入选用的是MIC芯片,输入频率范围50Hz~16KHz,经过反向比例运算放大电路(图中第一级放大部分)对电压信号进行放大,其模拟运放采用LM358,后面经过RC滤波、第二级跟随(模拟运放仍用LM358)后输出放大电压波形。
图1:MIC电压采集放大电路原理图
上面的MIC电压采集放大电路是典型的应用电路,依据MIC芯片输入频率的不同,会对后级的R(R5、R6、R7)、C(C2、C3)参数设计做调整。然而,这样的设计还是有问题的,可能会出现MIC输出的电压波形幅度有失真状况,异常波形可参考如下图2所示。
图2:MIC输出的电压幅值失真异常波形
那么,为什么会出现MIC输出的电压幅值失真呢,分析原因如下:
1、MIC很少直接使用100倍放大的,100倍放大至少需要使用2~3级放大才可以,而LM358第一级用了100倍增益放大(Au=-R1/R2),但LM358的带宽只有700kHz,这样意味着电路带宽只有7kHz,而且是在7kHz就有信号衰减了的,LM358本身在高频情况下输出范围也是严重压缩的,所以这里选用LM358不太合适,可参考如下图3所示的LM358输出摆幅与频率的关系图。
2、LM358也不是轨至轨输入、输出的,特别是第二级跟随,输入输出范围都会受限。
图3:LM358输出摆幅与频率的关系图
设计改善建议:
1、可以优化下放大电路的交流增益、直流增益及带宽,一个原则,尽量让放大电路的增益在Mic的拾音频率范围内,这样可以保证音频频率范围内的交流信号被放大,直流及带外噪声没有被放大。
2、推荐选用圣邦微的SGM722双通道低噪声运算放大器去做设计改善,高增益带宽可达11MHz,轨至轨输入输出,高转换速率可达8.5V/μs, 噪声低至8.5nV/√Hz @10kHZ,过载恢复时间0.6μs,工作温度-40℃~+125℃,支持MSOP-8封装,SOIC-8封装,其pin脚定义可参考如下图4所示。
图4:SGM722双通道低噪声运算放大器pin脚定义图
最后,提供下SGM722双通道低噪声运算放大器的输出电压摆幅与频率的关系图,参考如下图5所示,通过图中不难看出100KHz以内没有任何输出电压幅值跌落现象,性能非常出色,适用于高频应用。
图5:SGM722双通道低噪声运算放大器的输出电压摆幅与频率的关系图
通过上面的介绍,相信大家对圣邦微(SGMICRO)的SGM722双通道低噪声运算放大器的电性参数特性有清晰的认知,同时也对音频模拟运放设计选型也有所学习和收获,如果您感兴趣记得收藏和点赞哦,感谢!有问题请留言或电话联系世强400-887-3266。
