STM32U5 OPAMP usage with sine wave with voltage offset

Seokjin

Hello ST.

 

I would like to amplify a signal using the built-in opamp of the STM32U575ZIT6QU or STM32U575RGT6 product.

The signal I want to amplify is as follows:

  • The middle voltage is approximately 1.65V,
  • It has an normal amplitude in the range of 1.5V to 1.8V,
  • I would like to amplify this amplitude to a level such as 1V to 2.3V.

Is it possible to use the built-in op-amp in this scenario?

I would prefer to first consider using the PGA connected mode without external resistors or capacitors.

It would be greatly appreciated if you could provide detailed information on how to connect the circuit.

 

Thanks in advance.
