Preciso gerar um sinal senoidal de 20hz a 
20khz de amplitude fixa, boa qualidade e frequência variável 
com o CS4272-CZZ e STM32H750

Hello,

The answer is simply: read the datasheet of CS4272, seems it's working over SPI/I2C/I2S, and develop your library. This is not a question related to STM32. Find if the chip provider provided Application note for the chip.

PS: in next time please write in English.

Thank you for your understanding.

When you realy require external DAC learn use SAI STM32CubeH7/Projects at master · STMicroelectronics/STM32CubeH7 · GitHub

otherwise use internal STM DAC , too can generate less bits...
