Summary of UNIVERSAL OPAMP BOARD FOR SMD SOT23-5 PACKAGE
This small PCB hosts a single SOT23-5 op amp (LM321 recommended) and provides flexible wiring for single- or dual-supply operation, multiple input/output headers, a power LED, and jumper-selectable supply mode to support many op-amp circuits like filters, differential amps, and compensation networks.
Parts used in the OPAMP SOT23-5 Breakout Board:
- LM321 op-amp (SOT23-5) or any SOT23-5 op amp with LM321 pinout
- SOT23-5 PCB footprint
- Jumper J1 (to select single or dual supply)
- 4-pin male header connector for inputs
- 3-pin male header for supply input (single or dual)
- Power LED D1
- Resistor for LED (assumed on PCB)
- PCB (37.31 x 23.50 mm)
This is easy to build and very useful project for hobbyists and students to learn and create OPAMP-based projects. The project accommodates a single OPAMP in the SOT23-5 package. The project provides the user with multiple choices and extensive flexibility for different applications circuits and configurations. It provides the user with many combinations for various circuit types including active filters, differential amplifiers, and external frequency compensation circuits etc. A few examples of application circuits are given below.
