    Hi,

    Please have a look to the

    STM32L152 

    RM (

    http://www.st.com/content/ccc/resource/technical/document/reference_manual/cc/f9/93/b2/f0/82/42/57/CD00240193.pdf/files/CD00240193.pdf/jcr:content/translations/en.CD00240193.pdf

    ), in paragraph 15, you will have some details about the operational amplifiers (description, how to use the OPAMP output as ADC input, calibration...).

    I hope you will find what you need.

    BR. Jeanne
