Hi,
I've a dspic30f and i want to acquire an AC signal (+/- 10V) to do some amplitude and frequency analysis (up to the 40th harmonic - 2000kHz ).
How can i convert from a +/-10V signal to a 0V to +5V signal for ADC acquisition? Is there a IC capable of doing this job?
I suppose i can do this by using a couple amp ops (1 for offset, other with <1 gain), but i can't find any schematics for doing this.
Can someone help me?
Sorry for my bad English.
