hi all,
i am using dsPIC30f6010 microchip and i would like to know how to design a offset circuit for voltage signal to be in the range (0-5)v, if before applying it to the adc, voltage is in range -2.5 to 2.5V
thank u
hi all,
i am using dsPIC30f6010 microchip and i would like to know whether the designed offset circuit, (for voltage signal to be in the range (0-5)v if before applying it to the adc, voltage is in range -2.5 to 2.5), is correct and what type of opamp i have to use here?sorry i forgot to put the zener diode at the o/p of opamp.
how should i get the -ve voltage for -2.5V
thank u

thank u very much for ur support.
i am using dsPIC30f6010 microchip . for voltage signal to be in the range (0-5)v if before applying it to the adc, voltage is in range -2.5 to 2.5V (i.e nearly sinusoidal with peak-peak amplitude of -2.5v to +2.5V). I got this range of voltage after scaling down the sensed voltage( or current) using voltage (or current) sensor. now please tell me whether i can use the proposed circuit by u?
