Any possibility: Get ADC input on PA9

Hi,

this might be a stupid question because datasheet says there is no ADC in pin PA9 on a STM32F407VGT, 

so what i am probably asking is if there is any way of working around this / finding a hack?

Background is that we have an already produced PCB where the pin PA9 is routed to an analog sensor output and i need to read the analog signal somehow.

Regards,

Patrick

No.

Not in SW, as Jan said.

But if it is a QFP package it might be possible to bridge to an unused pin which is an ADC input?

Thanks for the answer. Ok i will try to bridge to another pin.
