Hi,
these days i have been working in a project that requires +5V and -5V voltages. The IC in question is the intersil ICL7107.
In the beginning i didn't know how to plug the wires to each battery so i could drive out the desired voltage. On my first two attempts, i accidentally blown two tantalum capacitors (2.2uF) on the LM7905 input. After reviewing my books, i came to the conclusion that i have been working with reverse polarity and i also accidentally misunderstood the pinout as my decision was to work with LM7805 and LM7905 and these two have different pinouts.
Okay, the question is this:
Is my schematic correct?. (PDF attached). Is that the correct way to drive out +5V and -5V from two 9V batteries.
Help will be graciously welcome
pd. Sorry for the graphics quality i didn't had time to make the schematic on the computer.
