Quad op-amp is a single package with how many individual op-amps?

• A. Two op-amps
• B. Four individual op-amps
• C. Eight transistors
• D. Three op-amps

Answer: (B)

A quad op-amp contains four independent operational amplifiers inside a single package. This means you can build four amplifier stages using one IC, often sharing power rails and the same substrate to save board space and reduce interstage parasitics. You’ll commonly see quad op-amps in parts like the LM324 family, which come in a single 14-pin package and provide four amplifiers together. Because of that, the number of individual op-amps in a quad package is four. The other options describe either dual or triple op-amps or refer to transistor count, which isn’t how these devices are defined.
