Hello, per the customer:
It was identified in the technical tests of our products, the component TL072 of the manufacturer Texas of the lot 1621012MY1, giving a difference in
value and consequently not functioning properly for the products. It was identified in the tests, that from 4KHz, the product has a significant drop in
response. At 18KHz the result is -8dB on the product.
2,500 pieces were used, and they are also being sent, but outside their encapsulation and with traces of solder.
hello, Please see the following photos. I hope that is what you are looking for. Please let us know if there is anything else that you need from us.
Hello,
A schematic would be something similar to the below image. Please make sure supply voltages and inputs and outputs are included.
Best,
Jerry
Hi,
because the frequency response of TL072 -like any other OPAmp- heavily depends on the set gain and other factors, a schematic would be urgently needed.
