It comes in the datasheet. Please refer to the <EM>4.4 Analog</EM> section.<BR /><BR />Hope it helps you. <BR /><BR />Have a nice day!</P> Thu, 23 May 2024 19:37:31 GMT _Leo_ 2024-05-23T19:37:31Z https://community.nxp.com/t5/MCX-Microcontrollers/MCxN947-OpAmp-voltage-input-limits/m-p/1871141#M368 <P>the document "AN14190: OPAMP usage on MCXN947" refers to different configurations for the opamps, but I could not find data on the input Max and Min voltages, furthermore there is an inverting configuration which has me confused as all the data that I've seen only refers to positive voltage values.&nbsp; So what are the maximum input and voltages for the OpAmps and what is the use case for the inverting OpAmp if negative voltages are not allowed.</P><P>&nbsp;</P><P>Thanks.</P> Wed, 22 May 2024 18:24:58 GMT https://community.nxp.com/t5/MCX-Microcontrollers/MCxN947-OpAmp-voltage-input-limits/m-p/1871141#M368 RuiF 2024-05-22T18:24:58Z https://community.nxp.com/t5/MCX-Microcontrollers/MCxN947-OpAmp-voltage-input-limits/m-p/1873985#M374 <P>Hi,<BR /><BR />Thank you so much for your interest in our products and for using our community.<BR /><BR />The analog electrical specifications/characteristics usually do not come in app notes.
