Hi expert,
The customer tested the normal operation current of TL074 is about 8mA at the VCC pin. On the datasheet, it shows that the supply current is 1.4~2.5 mA for each amplifier in no load condition. 8 mA is within this range. While the customer think 8mA Icc is a little high, they want to know if there is any method to decrease the operation current.
