Hi everyone,

What is the simplest way to create an AC voltage level shifter which will shift a 0-10V P-P signal down to +/-5V P-P? The frequencies I'm working with are from about 100Hz to 3KHz.

I would like to avoid using a negative supply if possible, but will if it is necessary.

 

Use a capacitor. The capacitor removes the DC offset and produces an AC output. Adjust the capacitor to get the required frequency response. I recommend 100nF to start off with. The capacitor must be rated for at least the Vp-p, I think.

It's important to note that the capacitor will attenuate the signal slightly.

EDIT: Added image.

 

Thanks Tom. I will give this a try first thing in the morning.

Just be aware that it only works for waveforms with 50% duty cycle, like sine waves and square waves.
