关于LM4766静音部分的计算公式,有一个费解的地方。根据PDF里的静音电阻(4脚和6脚之间)计算方法得出的结果不超过5K,而网上LM4766的典型电路上的这个电阻都在10K以上,不知何故?
附:
一、PDF中该电阻的说明“Mute resistance set up to allow 0.5mA to be drawn from pin 6 or 11 to turn the muting function off.
--->Rm is calculated using:Rm<(|Vee|-2.6V)/I where I>0.5mA.Refer to the Mute Attenuation vs Mute Current curves in the Typical Performance Characteristics section.”
