“Op-Amp”Operational Amplifier • Non Inverting Amplifier • Inverting Amplifier • Adder • (and Subtractor using an Inverter) • Differential Amplifier • Integrator • Differentiator Op-Amp name derives from early usage of these elements in performing mathematical operations in analog computers.
Three Ways to Examine Op-Amp Behavior • Consider as an Ideal Op-Amp Component • Consider as a Feedback Model and Examine Behavior • Perform Conventional Circuit Analysis
VE = VIN+ - VIN- VOUT = a * VE VIN- VIN+
Ideal Op-Amp Model VE = VIN+ - VIN- VOUT = a * VE
