AD8079BR-REEL Application Field and Working Principle

The AD8079BR-REEL is a low power low noise, low distortion amplifier specifically designed for use in field instrumentation applications. This amplifier is suitable for biomedical engineering, motor control circuitry, general audio, robotics and other industrial and consumer applications.

Application Field

The AD8079BR-REEL can be used in a wide range of applications including automotive and vehicle instrumentation, process control and recording systems, as well as in medical diagnostics and monitoring systems. Additionally, it is used in low noise signal conditioning systems and high frequency loudspeaker crossovers.

The AD8079BR-REEL is especially well suited for the demanding conditions of portable and field instrumentation where power efficiency, wide input voltage swing and low noise operation are required. It combines low distortion (0.001%), low offset voltage and wide bandwidth to provide excellent signal performance.

Working Principle

The AD8079BR-REEL is an integrated circuit that contains three amplifier stages: a differential input stage, a mid-level adjustable gain stage and a low noise, low distortion output stage.

The differential input stage consists of two transistors connected in a differential amplifier configuration. This circuit provides an excellent input impedance and low offset voltage.

The mid-level adjustable gain stage is an adjustable gain amplifier that can be used to adjust the overall gain of the amplifier.

The low-noise, low-distortion output stage consists of two transistors connected in a differential output configuration. This configuration provides a high open-loop gain, low source impedance and low noise output.

The AD8079BR-REEL is also equipped with a power-down mode that can be enabled by setting the shutdown control pin to a low logic level. This mode reduces power consumption when the amplifier is not in use.

Conclusion

The AD8079BR-REEL is a low power, low noise and low distortion amplifier specifically designed for use in field instrumentation applications. Its low distortion, low offset voltage and wide bandwidth provide excellent signal performance, while its power-down mode reduces power consumption when the amplifier is not in use.
