MP Posted September 26, 2004 Report Share Posted September 26, 2004 C6 and C7 are bypass caps for the supply lines. Depends upon how you are powering this device as to whether you need them or not. You can leave then out in the initial design and add them if needed. No harm will come to the circuit without them.The value will depend upon how much filtering is needed.MP Quote Link to comment Share on other sites More sharing options...
