Hello, I used two ADA4870 to constructed a 2 stage non inverting gain amplifier with VCC=36V, VEE=-4V for the high rail and low rail of the opamp. When a 0.3V input voltage is supplied to the gain amp input, the measure output is 5V which is higher than the expected value. Anyone have any idea what cause this to happen?
