Is it still applicable to get +5V from -5V using the ICL7660? I'm asking this because in the datasheet they only mention converting positive voltages to negative voltages. I'm interested in converting from negative to positive voltages.
So you're saying that "let's say I use a voltage divider as a sensor to output -5V from input of -100V then I use an inverting amplifier to get a positive 5V" ?

I'm using ADC of dsPIC30f4011, and LM358N op-amp.

Hi y'all,
I have a converter that is designed to output a -100V but now I find it challenging to read that on ADC. My first approach was to use an inverting amplifier with a gain of 1, the problem is that i'm not sure if the op-amp will be able to handle 100V because most of the amplifiers are...
Oh shoot!!!! for some reason I used a 270ohm resistor instead of a calculated 5.6 ohm resistor..

I'm testing it on a vero board, i'm not sure but i think i can handle up to 3A if i'm not mistaken. I stand to be corrected!
I do have a gate driver circuit, i used the HCPL 3120 gate driver but the problem still persists. how much more current specifically? the HCPL that i'm using gives out 2A.
Hi y'all
I'm trying to drive the MOSFET directly with the PWM. I generated a PWM signal using dspic30f4011 and because the MOSFET needs atleast 10V to switch on. I then used a MOSFET gate driver (HCPL 3120) to boost the voltage.
I get a nice clean gate signal but immediately when i connect...
Hi y'all,
I have build 3 voltage divider circuits for sensing DC voltage, the output of this voltage dividers will then be fed to 3 analog channels of the dspic30f. the problem is once i interface the two circuits(voltage divider and dspic30f) the output voltage of 2 of the voltage dividers...
