A adinogcas New Member Feb 26, 2010 #1 Just quick question... What is the output of this circuit? (suppose Vdac=0=GND) Ip=Photo current will it be Vo= -Ip * R or V0=Ip*R? And why? Because someone told me it should be -Ip*R not Ip*R. And most of transimpedance circuit use in different configuration. I am getting confused here. Please help!
