Hello,
we got a very very mature design were the current consumption of the device is critical.
Older Devices we got in our lab stock are marked with 42AD and got a dent near Pin 1
All of that devices show a current consumption of about 3.5 mA at no load +/- 5 V supply.
Our manufacturer got devices wich are marked with 8C2N with no detent but a laser marking for pin 1.
All of that devices show a current consumption of about 5.5 mA at no load +/- 5 V supply.
Theese devices seems also to be a little bit faster than the older ones.
The +2mA current causes troubles in our circuit, which should not to be changed.
As i found no PCN were a change of the circuit was mentioned i am wondering if that behaviour is just bad luck, or a counterfeit or if there was a change of the product in the past ?
