  General Purpose OPAMP Moderate values of the key parameters • Current differencing OPAMP ( have different internal structure) • Non-inverting input is derived from inverting input • Current mirror circuit is used

Operational Amplifier • Number of differential amplifier in cascade. • Integrated circuit • High Gain • High input impedance • Low output impedance Basic OPAMP  

     OPAMP applications   • Linear Application : Output changes in  accordance with input. Example : inverting amplifier, voltage  buffer, non-inverting amplifier, current  controlled voltage source etc. • Non-linear Application : Output wave shape is different from that of input signal.  Example : Differentiator, integrator, Comparator, Schmitt trigger, Zero crossing detector etc.
