Operational Amplifiers, Part 2

SKU: ICOA200CENDuration: 60 Minutes

Operational amplifiers, or op-amps, are widely used in electronic instruments. Instrument technicians must be able to recognize basic op-amp circuits on schematic diagrams and, given certain input conditions, must be able to determine proper output conditions. Instrument technicians must also be able to isolate faults and replace faulty components in instruments that use op-amp circuits. This course is devoted to solving typical troubleshooting problems involving basic op-amp circuits.
