Hello sir,
I want to use the opa547 in my one application & i do not want any offset at output. for testing purpose i have assembled the opa 547 circuit on general purpose board. right now i am providing power supply of +12v w.r.t. gnd & i am getting offset of 600mV. it is clearly written on datasheet of opa547 for VO=0V use -1V on pin number 4. can i use negative voltage reference? Can you please suggest me any -ve voltage reference from positive supply?
