Product Description

The Op Amp Proto SOT23 circuit board is designed for rapid prototyping of operational amplifier circuits using popular 5-pin SOT-23 packages with the output on pin 1, non-inverting input on pin 3, and the inverting input on pin 4. It can be configured as an inverting or non-inverting topology with selectable input and feedback resistors and has a parallel feedback capacitor for filtering or compensation. The board measures 1" x 1" and includes 4 .1" dia. mounting holes that are isolated from GND. Amplifier circuits can be easily designed and assembled with standard 0603 surface-mount passive components. It includes provisions for input and output DC blocking capacitors, or these can be replaced with zero-ohm jumpers for DC operation. Separate bias pads are provided for single and dual bias configurations. Use caution on the bias polarity depending upon the specific op-amp being used.

Features

• Fits standard 5-pin SOT-23 op-amp packages
• Inverting or non-inverting configuration
• Optional DC blocking/AC coupling capacitors at input and output
• Uses standard 0603 passives

Why I Made This

This board was made to help scale-down analog voltages before they went into the A/D input of an MCU.

What Makes it Special

It allows you to prototype many op-amp circuits and it's low cost.
