Evaluation boards are created to analyze, experiment, and gain a better understanding of a certain electronic component. Op-amp evaluation boards, such as the DEM-OPA-SO-2E, are particularly useful for studying how various external conditions, such as power supply and load current, affect the performance of an operational amplifier. In this article, we will discuss the DEM-OPA-SO-2E application field and working principle.

Application Field

The DEM-OPA-SO-2E is a single-slope monolithic operational amplifier. It is mainly designed for low-power applications such as stress monitoring and portable medical instruments. Moreover, its small size and low power consumption make it ideal for use in high-density printed circuit board assemblies, and due to its low input bias current it is suitable for use in high-impedance applications.

Working Principle

The DEM-OPA-SO-2E operates in a single-slope linear configuration. The amplifier consists of a three-transistor differential amplifier, a gain stage, and a voltage-follower stage. The first transistor acts as the input differential pair, while the second and third transistors form the current-mirror gain stage. This amplifier provides a gain of 72 dB at a single frequency.

The DEM-OPA-SO-2E is powered by a single voltage source, which means it can be used in battery-operated systems or anywhere a single-battery supply is needed. In order to ensure stable operation, the amplifier requires low input offset voltage, as well as low supply-current variation and minimum environmental sensitivity.

In order to take full advantage of the DEM-OPA-SO-2E’s performance, careful capacitor selection is needed. This will ensure that the amplifier is properly compensated and that it delivers the highest possible closed-loop gain. Additionally, the DEM-OPA-SO-2E’s high stability means that it can be used in a variety of noise-sensitive applications, without compromising the signal integrity.

Conclusion

The DEM-OPA-SO-2E evaluation board is a useful tool for understanding the parameters which affect the performance of an operational amplifier. It is especially suitable for low-power portable applications which require high stability and low sensitivity to environmental factors. Moreover, careful selection of components is necessary to optimize the amplification capability. In conclusion, the DEM-OPA-SO-2E is an ideal solution for affordable, high-performance operations in battery-operated systems.
