Hi Folks,

I have an analog signal source vary from -40mv to +1100mv, and I want to swift entire range from 0mv to 1400mv. It can be easily done by adding 40mv
by simple math. Yet, if I want to add the offset using some hardware, how can I do it? The signal that will eventually go through an op-amp (LM324)and the op-amp may have a gain of 3.57 to bump it up to a range of 0 to
5volt and feed it to Analog to Digital. The reason that I want to swift the signal to positive range cause my board was configured to only accept 0 to 5 volt (Vref-low and V ref-high).

Thanks,


Clement
