In a quad op-amp chip, how many individual op-amps are present?

• A. 1
• B. 2
• C. 4
• D. 8

Answer: (C)

A quad op-amp chip contains four separate op-amp blocks on one silicon die. The term “quad” in IC naming denotes four amplifiers per package, just as a “dual” would denote two and a “single/mono” would denote one. In a quad device like the common LM324, you have four op-amp channels, each with its own inputs and outputs, though they share a common power supply and some internal biasing. So the number of individual op-amps present is four.
