Are the TLV2372's surroundings and pin connections correct ?

STM32F030F4P6TR'nin PA5 pininde PWM araştırmaları. TLV2372ID ile 0-10V analog çıkış elde etmeyi planlıyorum. Devre şemasının doğru olması gerekiyor. TLV2372'nin sınırları ve pin bağlantıları doğru mu?

English is not my native language either, but it is the language of communication defined by the community, which is why I am responding in English here.

For 0...10V, an opamp with approximately three times the gain is required (3.03, to be precise) if you have a VCC of 3.3V. According to the connection diagram, you have wired it correctly, although a drawing of opamps with a classic triangle would be clearer and better readable for the supporters here.

Please note: even though the TLV2372 is an RRIO opamp, it will output a significant output voltage of approx. 200mV at a VDD of 12V and very low input voltages close to 0.

Good luck!
