I have a four channel op amp (0745 LT1369CS is the top markings) I have a supplied 12V and a regulated 5V. Pin 1 is 5A with pin 2 as feedback. All of the other channels read 4.99-5.00V. Channel A is pulled low to ≈ 2.8V. I have raised the legs on channel A of the op amp to isolate it from the sensor board downstream. When I raised the legs and tied the output to the feedback I still get 2.8V. I have replaced the chip twice. Any one ever ran into this? It is supposed to put out 5V precision.
