Introduction

ADA4927-2YCP-EBZ evaluation boards are designed by Analog Devices, Inc and are part of their Op Amps evaluation boards suite. These evaluation boards are used to evaluate the features and performance of the ADA4927-2 family of low noise, low-power, high-speed operational amplifiers. This evaluation board is configurable and can be used to evaluate the many features of the ADA4927-2 amplifier family.

Application Field

The ADA4927-2YCP-EBZ is suitable for a wide range of applications. It is mainly used in industrial applications such as motor control, power supply control, HVAC, audio processing and consumer electronics. The board’s low-noise, low-power, and high-speed capabilities make it a good choice for these applications. The board is also suitable for use in audio processing, where its low-noise characteristics enable signal processing with higher resolution and higher fidelity.

The amplifier is also suitable for precision sensor applications requiring a low-noise, low-power, high-speed amplifier. It is well-suited for measuring signals from precise temperature, pressure, and motion sensors. The board’s low distortion, low-noise, and high-bandwidth characteristics help reduce the effects of noise which may otherwise degrade measurement accuracy.

Working Principle

The ADA4927-2YCP-EBZ is an operational amplifier, which is a voltage amplifier that responds to differential or single input signals. The amplifier operates over a wide range of supply voltages, from 2 V to 5.5 V, and at an operating current of 6 mA per amplifier. It features unity gain bandwidth greater than 400 MHz, low input-referred noise of 4 nV/√Hz, and a slew rate of 360 V/µs. The amplifier also has a -3 dB bandwidth of 350 MHz, can drive of up to 4mA of output load capacitance and has high common-mode rejection rate (CMRR) of 90 dB.

The board also has zero crossing and current limiting features, for applications requiring low-distortion audio amplifiers or current-limited output. It is designed to operate in most common single supply amplifiers operating at a supply voltage of 3.3 V. All input and output pins of the board are well placed to support application level circuit layout.

The board also has an on-board jumper, which enables the user to select between single and dual-channel functionality. The channel selection enhances the speed and flexibility of the amplifier for applications that require simultaneous operation on two channels. The board also includes a test point terminal, which allows for easy measurements of voltage and current.

The ADA4927-2YCP-EBZ is targeted for both low-power, high-performance and low-noise, low-power applications.

Conclusion

The ADA4927-2YCP-EBZ evaluation board provides an easy and convenient path to evaluate the features and performance of the ADA4927-2 low-noise, low-power, high-speed operational amplifiers. It is suitable for a wide range of industrial, audio, and precision sensor applications. The board offers a range of performance characteristics and features, including a high-gain bandwidth and high common-mode rejection rate, as well as an on-board jumper for channel selection and a test point terminal for easy measurements. This evaluation board is a great choice for applications requiring high performance and low-noise at a low power level.
