Hi all

 

I am using SSM2166 in my audio circuit.

The datasheet has graphs of

 

  Figure 5. Noise Gate vs. RGATE (Pin 9 to V+)         NOISE GATE in y axis and RGATE in x axis.

  Figure 9. Rotation Point vs. RROT PT (Pin 11 to V+)   ROTATION POINT in y axis and RROT PT RESISTOR (kΩ) in x axis.

 

Wrt Figure 5,If i set the noise gate to say 1mVrms,does it mean

the i/p signal to the buffer below 1mVrms will be attenuated?

Or

the i/p signal to the VCA ( mic input multiplied by buffer gain) below 1mVrms will be attenuated?

 

Please help me.

Thanks & Regards

Sreelakshmi R
