whomper Posted August 30, 2008 Report Share Posted August 30, 2008 Hi,After succesfull usage of the AOUT_NG in my SEQ3, I have decided to go and build a MIDIBox CV with the NG. So, I have finally connected the AOUT_NG to my newly built CV box, only to find out I get no CV signal at all.I am testing +-15V in TL074 as well as 5V in TLV563. I get -1.195 in JP1 and -2.264 in JP2 and so on.Also, I have ~1.9V in pin 3 of the TLV563.In addition, resistors R33-R48 get hot while the +-15V is active.Any clues as to how to further debug this?Whomper Quote Link to comment Share on other sites More sharing options...
whomper Posted September 1, 2008 Author Report Share Posted September 1, 2008 I have made some more checks and it appears as if the TLV5630 does not produce any signal in all its lines.Might there be damage to the IC?Whomper Quote Link to comment Share on other sites More sharing options...
