Tried to piggyback two AK4395 dac chips

sendler · 3rd February 2009, 07:34 PM

I tried to piggyback a couple AK4395 dac chips last night but the legs are a little too short to reach down from one chip to the other. They are very small and hard to work with. It's too easy for the chips to get really hot while trying to solder them. Looks like paralleling dac chips will have to be left to those with boards that are designed for it. Might not help much without having separate output resistors for each chip's output to prevent one chip from current hogging anyway. I'll have to see if I can come up with a way to make a header onto a new circuit board in order to try it.

thru-holes, one chip at the top, the other at the PCB bottom Other electrical transitions from one side on to another should be done as close to pins as possible with (if posible) 2 thru-holes per transition.
