The OP-amp can amplify both a.c. and d.c. signals. An integrated circuit known as an operational amplifier (Op-Amp) amplifies the difference between two input voltages and generates a single output.
What OP-amp can Amplify:
- An operational amplifier is a voltage amplifier with a very high gain.
- By boosting the signals’ amplitude, it is utilized to magnify them.
- Both DC and AC signals can be amplified using op-amps.
- When two input signals differ, the ideal Op-Amp detects this difference and amplifies it to create an output signal. The voltage at the output terminal measured concerning the ground is known as the output terminal.
- A voltage-amplifying device called an operational amplifier, or op-amp for short, is created to be utilized with external feedback elements like resistors and capacitors between its output and input terminals.
- Under the many feedback topologies, whether resistive, capacitive or both, the amplifier can perform various operations, giving rise to its name of “Operational Amplifier.”
- These feedback components dictate the resulting function or “operation” of the amplifier.

Summary:
The OP-amp can Amplify 1. a.c. signals only 2. d.c. signals only 3. both a.c. and d.c. signals 4. neither d.c. nor a.c. signals.
Both a.c. and d.c. signals are amplified by OP-amp. Operational amplifiers (Op-Amps) are integrated circuits that amplify the difference between two input voltages and produce a single output.
