Hey everyone
I need to connect a large size of 8X8 matrix with max7219
what should I do
if I connect it directly then my max7219 ic is getting damage
please help me out
Please explain why you think the MAX7219 is being damaged. It is designed for an 8 by 8 matrix.
if I am using it for a small 8X8 matrix then there is no problem
but if i am connecting this with a large size of led matrix of 8X8 which require more currents then it is getting damage
can I use one more current driver IC like uln2803
The chip controls the current not the load. You set the current with a single resistor so the chip can not get damaged.
Now please post a link to the matrix you are using.

That tells us how long it is. But it is not a link. A link the the product will help us determine what you are trying to use. Without that we are guessing and our recommendations will be of poor quality.
