Hi All,
I'm using a THS4521 to measure a differential signal. I use Vcm to give the amplifier a common mode voltage off 1/2VCC to prevent clipping in ADC and the amplifier. The problem now is that the input signal is not bi-polar (Vin>=0V), but the ADC input is bipolar. I would only use half the range of the ADC.
It there a way to offset the amplifiers output differential? Something like below?
Best regards,
[EDIT]
Well I just tried it and this did the job. But the amplification had to be doubled to cover the positive and negative range ;)
