14 bit DAC
Hi
it seems simple, but you need basic knowledge about electronics, more presicely op-amps. You didn't mention the operation frequency, so yo need to care about it when selecting an op-amp.
First you attenuate your signal by a factor of (3-(-3))/10= 0.6 -it can be done with a voltage divider- then using an op-amp substrac from the resulting signal a dc voltage of -3Vdc, then your input signal can vary from 0 to 10V, but it is conditioned to the adc input voltage.
cheers
