TL074 max supply current for each Op is 2.5mA. In my operation, I measure total current from supply voltage. 10mA for +15v. 20mA for -15v. Base on this operation, I have the following questions: 1. Is max input supply current for TL074 2.5A * 4=10A ? Or based on Iik input clamp current spec 50mA? What’s the max power spec of TL074 2. If I calculate Tj of Tl074 not over spec 150 degree, should I still need to worry about the total power consumption and max input current spec?
