THEORY:
The input signal Vi is applied to the inverting input terminal through R1 and
the non-inverting input terminal of the op-amp is grounded. The output
voltage Vo is fed back to the inverting input terminal through the RF ,R1
network, where RF is the feedback resistor. The output voltage is given as,
Vo = - ACL .Vi
Here the negative sign indicates that the output voltage is 1800 out of phase
with the input signal.

Theory:
The input signal Vi is applied to the non - inverting input terminal of the op-
amp. This circuit amplifies the signal without inverting the input signal. It is
also called negative feedback system since the output is feedback to the
inverting input terminals. The differential voltage Vd at the inverting input
terminal of the op-amp is zero ideally and the output voltage is given as,
Vo = ACL .Vi
Here the output voltage is in phase with the input signal.

2. +Vcc and -Vcc supply is given to the power supply terminal of the Op-
Amp IC.
