Hi Grzegorz,100nF would be a good chose. You can use the maximum current but you have to watch the power dissipation to make sure it's under 4 watts. The power dissipation will be affect by the supply...

Thx, csmyth! I've got the reason for this problem. To read what you have written into the TGC registers, the 0th register should be set as "0x000006", making a distinction between the read of...

Hi Mariusz,TOD in the data sheet is chip-to-chip variation spec. in a multi-chip system. For a single-chip application, all channels have same TOD for beam forming.Regards,HK

Thank you for your reply sir, I wrote that register as 0x0003 and i got the output, but its routing all eight input channels. That means it enables every input channels and gives output.
