Evaluation boards are an essential choice for creating solid designs without having to worry about the technical details associated with building circuits. While boards can be designed for many different types of components, the LMH6552SDEVAL/NOPB is an evaluation board specifically designed for use with op amps. This article will provide an overview of the LMH6552SDEVAL/NOPB’s application field and working principle.

Application Field: The LMH6552SDEVAL/NOPB is an evaluation board for the LMH6552 op amp, which doubles both as an amplifier and as an adjustable gain buffer. This is ideal for high performance, high frequency applications. It is primarily designed for use in consumer and automotive audio applications, audio amplifiers and if frequency scalers, high speed PID controllers, and power amplifiers. Due to the low input offset of 0.9 mV maximum, it is power- and ground-efficient, making it an ideal choice.

Working Principle: The LMH6552SDEVAL/NOPB utilizes a unity gain buffer configuration to amplify the input signal and provide adjustable gain. This is accomplished by connecting the output of the op amp directly to the inverting input, allowing the gain to be adjusted via the feedback resistor. The input signal is connected to the non-inverting input, where it is then amplified and outputted. This operation is consistent over a wide range of frequency sums, allowing the LMH6552SDEVAL/NOPB to be used in a variety of applications.

The LMH6552SDEVAL/NOPB is further adjustable with programming settings such as gain, slew rate, and other external components. With the available accessories, the board is adaptable to a wide variety of application requirements.

Additionally, the LMH6552SDEVAL/NOPB offers protection from common voltage faults and over current or over temperature conditions. It has multiple protection features such as overtemperature detection, short-circuit protection, and an internal thermal shutdown mechanism.

In summary, the LMH6552SDEVAL/NOPB is a versatile and highly efficient evaluation board designed for use in consumer and automotive audio applications, audio amplifiers and frequency scalers, high-speed PID controllers, and power amplifiers. It utilizes a unity gain buffer configuration to amplify the input signal and provides adjustable gain. It is further adjustable with programming settings and offers protection from common voltage faults, over-currents, and over-temperatures.
