Compare your scheme with the tracks lay-out, check it’s nescessary Voltage 12 up to 16VDC and compare the scheme with the ic outs.Possible you work with a damaged ic, so replace if an other new one works well. Don’t you miss a pot. at the input? Your scheme is probably a test circuit.The circuit with the load to ground will probably work better, I guess.This is an application.
