(yellow line: non inverting input
blue line: output of OPAMP )
Hi,
I am using the NUCLEO-F303RE board and now I am testing the OPAMP3 , which is one of the peripherals in STM32F303.
I have set the PA1 as non inverting input, PB2 as inverting input. And I input differential signal (up to 400kHz) to OPAMP3. It seems that the voltage OPAMP output is too low.
According to official manual, the GBW of OPAMP is 8Mhz. But now this OPAMP has bad performance when input signal is 400kHz.
How do you think about it?
