SparkFun OpAmp Breakout - LMV358

The SparkFun OpAmp Breakout - LMV358 is a compact, 5V operational amplifier breakout board. This board is designed as a two-stage amplifier with a gain of 100, providing 10x gain at each stage. The unique feature of this board is its on-board trim pot, which adjusts the signal level between the stages, rather than the feedback path.

The board offers a bandwidth of 15.9kHz, which is set by a pair of feedback capacitors. However, if you need a wider bandwidth, you can remove the capacitors to achieve over 100kHz. The LMV358 operational amplifier used in this board can source up to 160mA, making it an excellent choice for low impedance driver/buffer applications.

The SparkFun OpAmp Breakout - LMV358 is ideal for a wide range of applications. For instance, it can be used in audio processing systems to amplify signals, or in sensor systems to improve signal-to-noise ratio. It's also perfect for hobbyists and students who want to learn more about operational amplifiers and their applications.

The board comes with comprehensive documentation, including a schematic, Eagle files, and an introduction to operational amplifiers with LTSpice. Also, the datasheet for the LMV358 opamp is provided for detailed specifications and application information. For those interested in modifying the design or understanding it in-depth, the design files are available on GitHub.

One of the unique properties of the SparkFun OpAmp Breakout - LMV358 is its compact size. Despite packing a two-stage amplifier and a trim pot, it measures only a few millimeters across. This makes it easy to integrate into existing projects or systems.

With the SparkFun OpAmp Breakout - LMV358, you are not just getting a simple operational amplifier breakout board. You are getting a versatile, high-performance, and compact tool that can significantly enhance your electronic projects and applications.
