Hi everybody/anybody.
Im trying to configure my first (and basic) LM741 op amp inverter.
My Vcc is +5V, my input is a 1.5v DC battery, the positive connected to the inverting input pin 2, and the negative connected to non-inverting input pin 3.
Rf is 473k, Rin is 220k, so looking for a gain of about 2, and therefore looking for an output of about -3v, or thereabouts.
But using my multimeter, +ve lead on output, -ve lead on V-, I measure +2.06V
What am I doing wrong?
Thanks in advance
matthew
