When an integrated circuit says that it is a dual op amp, that means that it has 2 operational amplifiers in the circuitry. Not to be confused with single/dual supply. Both briefly explained below.

Always consult the manufacturer datasheet of the particular component you are interested in for the most accurate information!

Basic properties

At the time of writing this, the kit linked above contains a variety of common op amps (including the LM358) and other ICs. As an Amazon Associate I earn from qualifying purchases.

Dual op amp means there’s 2 op amps in a single package.

Quad op amp means that there’s 4 op amps in a single package.

Each op amp in a single integrated circuit (IC) (package) shares the same power (Vcc/GND/Vee etc.) pins as the other op amps in the IC.

Single/Dual supply

Note: Single and dual are also used to indicate the preferred power supply, which a dual op amp may be made especially for just one, or both types of power supplied.

Single supply: The most negative point of the circuit and power supply is the 0V reference point (ground). Best for direct current (DC) applications.

Dual supply: One supply voltage is more positive while the other supply voltage is more negative than the 0V reference point (ground). Best for alternating current (AC) applications.
