Dear team,
My customer would like to configure function of differential to single-ended using one op amp.
- Input signal : +-2.5V differential signal , Vp-p : 5V
- output signal : 0 to 3.3V output for ADC input.
I would like to use below concept with single supply. please review it and let me know whether this concept is available or not.
If above concept is not available, please recommend right solution to configure customer requirement.
Thank you.
Hello Clemens, Robert,
Thank you for your comment.
but the customer can't change their schematic and layout this time. so I would like to recommend below schematic for customer application.
Please review below schematic and TINA simulation and let me know your opinion regarding concern points.
- Input signal : +-2.5V differential signal
- output signal : 0 to 3.3V output for ADC input.
==> Is it available to input negative voltage at TLV9054 Input with single 5V supply?
Thank you.
Hi Dino,
What's important isn't if the signal goes beyond the supply rails but rather if the voltage that the op amp sees goes beyond it's supply rails.
Not seeing any issues with your circuit since you have shifted the signals common mode voltage by the time it reaches the input pins of the op amp.
Best Regards,
Robert Clifton
