Package Information
The 741 op amp is available in various packages, including the 8-pin DIP (Dual In-line Package), SOIC (Small Outline Integrated Circuit), and TSSOP ( Thin Small Outline Package). Let’s explore the package information for each type.
DIP Package
The DIP package is the most common and widely used package for the 741 op amp. It has 8 pins, with the power supply pins located at opposite ends of the package. The pinout is as follows:
| Pin Number | Function |
|---|---|
| 1 | Non-inverting Input (+) |
| 2 | Inverting Input (-) |
| 3 | Output |
| 4 | Not Connected (NC) |
| 5 | Not Connected (NC) |
| 6 | Power Supply (Vcc) |
| 7 | Power Supply (Vcc) |
| 8 | Ground (GND) |
SOIC and TSSOP Packages
The SOIC and TSSOP packages are smaller alternatives to the DIP package. They have similar pinouts but with a different pin configuration. The SOIC package has 8 pins, while the TSSOP package has 14 pins. These packages are suitable for applications where space is limited.
