Dear Expect:
TL072CDR, it's current is smaller than that of previous supplies. customer would like to confirm whether the current gap between different batches is so large? What's the reason?
The following are the parameters of the technical test:
The operating current of the TL072 single op amp of TI used in production now: 3.5mA
The operating current of the TL072 single op amp of last year's batch TI: 8.4mA
When all potentiometers play the middle through the op amp is 1 to 1:
ST TL072 TI TL072(Now in mass production) TI TL072(From the old prototype)
operating current: 105 mA 54mA 107 mA
The maximum non-distortion is less than 1%: 3.9VRMS 5.4VRMS 3.7VRMS
Background noise in the straight-through state: 32uVRMS 36uVRMS 32uVRMS
