Other Parts Discussed in Thread: OPA684 , OPA2684 , LMV7239 , LMV7291 , TINA-TI , LMV7271 Hi E2E,
My customer is simulating the OPA2684 and the OPA684 in TINA. The sim works fine until he imports the LMV7239 comparator. Once imported, TINA fails to find an…
Hi Naresh,
Do you have a schematic? Which comparator product are you attempting to apply? TI has comparator products available from three different linear product groups. An Applications Engineer who is associated with the particular comparator you have…
Other Parts Discussed in Thread: TPS40200 , LMV7271 , TL7702A TPS40200 typically turns on when input voltage is ~4.6 VDC. We need to keep the device off unitl the voltage reaches an input voltage of ~+30 VDC. Any ideas on how to do this. This will be a high…
Hi Thibault,
I agree with your assessment that the 1.6mV measured on the + input is most likely due to bias current flow out of that pin (1nA x 100k = 1mV typically) and in your case you have 1.6nA current. It appears that reducing the 100k resistor should…
