STM32F446 Tempreature Sensor, ADC

[Yoshimitsu_Manji_clan]

I am trying to read ADC value of internal tempreature sensor of my STM32F446 board. The data sheet says that the temp sensor is connected to ADC1_IN18 (page no. 37/198), but there is no such pin in STM32F446xx pin and ball descriptions. Can someone please help me from which pin can I extract the analog value of temperature sensor ?? 

Thanking you in advance..

As it's an internal sensor, it is not brought out to a pin, and is connected to ADC internally.

Hello @Yoshimitsu_Manji_clan  and welcome to the community,

You need to refer to the reference manual of the product RM0390 / figure 79

As you can see some ADC inputs (Temperature sensor, Vref, VBAT) are connected internally and not exposed on pins.
