Chapter 14 Operational Amplifiers
Introduction • Operational Amplifiers are integrated circuits (IC’s) that have a number of advantages over the standalone transistors. • Circuit Symbol and IC Pinouts
Ideal Op-Amp (page 664) • The circuitry of an operational amplifier with a closed, negative-feedback loop will adjust its output in any way possible to make the inverting input and non-inverting input terminals of the device equal in voltage. • Infinite Input Impedance • The inputs draw no current.
Inverting Amplifier • How does Vout depend in Vin? • Is there a phase shift between Vout and Vin?
Non-Inverting Amplifier • How does Vout depend in Vin? • Is there a phase shift between Vout and Vin?
Voltage Follower • How does Vout depend in Vin? • Is there a phase shift between Vout and Vin?
Example Problems • Example 14.1 • P14.11 • * P14.10 • * P14.20 • * Figure 14.8 (a) and (b) • * P14.9
Difference Amplifier • How does Vout depend in Vin? • Is there a phase shift between Vout and Vin?
