rereading the original email, I see that the actual desired voltage range is 0V
to 3.3V, not 3V. This is a non-inverting gain of 27.5% and an inverting
gain of -27.5% for a level shift of 1.375V from a -5V reference. Both
can be achieved with the same resistor pair again (120k and
33k):</FONT></SPAN></DIV>
