5 IC-Sockets / ICs
With ICs (integrated circuits), it is essential to observe correct
polarity. Most ICs will be damaged or destroyed when mounted
incorrectly. The mark on the silkscreen must match the notch
on top of the IC.
Pin numbers are counted
counter -clockwise, starting from the
notch.
Note: Please also pay attention to the ESD warnings at the
beginning of this manual. ICs are very ESD sensitive.
This
applies especially to the AD9833, which can be destroyed
even by a minor electrostatic discharge event!
