Hello,

This terminal is usually connected to signal ground via a 1M resistor and a .1uF and a .001uF cap.

Regards.

Hello!

Have I understand you correct?

Hello,

Sorry for the unclear description, the resistor should be in parallel with the caps (see below picture)

Regards.

Ok, but I have asked about GND_DRAIN pin (In datasheet it is pin 7 ) but you have connected pin 4(gnd) and 7( gnd in your variant, but gnd_drain in mine one) to ground directly. Only two shields pins you have connected by this way. What is correct? And where should I connect pin 7? Same directly to GND?

Hello,

If you have separate ground planes for power and signal, then connect Pin#4 to the power_ground and connect Pin#7 to the signal_ground, if your ground is the same for power and signals then you can connect Pin#4 and Pin#7 together.
