GND lead in a mixer chip

[jackreloaded]

Hi,

I'm using a mixer chip with 8 leads, 4 leads are GND
My question is, should I connect the 4 GND leads to my circuit board GND or it is enough to connect only one of the 4 GND leads to the board?

Thanks

As a general rule, connect all the Gnd leads to the appropriate 0v onnection on the circuit board.

I thought maybe they are connected together inside the chip..
Thanks for your help

They likely are but, particularly for high frequencies, you want the Gounod connection to be as low impedance as possible, so they connect the chip to ground at more than one spot.
