Hello,

I have +-1.5V signal in the end of ADC design of OPA 698.

I would like to connect this circuit with UART module which accepts 0-5V single ended signal.

How can I establish the connection? I have tried a simple comparator design but I could not succeed.

Thank you

Hello,

I need a system in the attached file below. OPA 698 gives me an output signal +-1.5 volts. On the other hand, FT232R accepts 0-5V single ended signal. I need to introduce this signal to the UART modul FT232R.

Hello,

You havent provided any information on the distortion and bandwidth acceptable. please see attached simulation to see one possible way of doing this.
