i designed a circuit using uA741 from ST https://www.st.com/stonline/books/pdf/docs/5304.pdf in order to amplify voltage using a gain of 22 ( R2 = 22k and R1 = 1k), the shematic is attached, but without résult the circuit is unfonctionnel, the pin 7 i used a 5V alimentation and in pin 4 i connect the ground,
