It is used in industrial, medical, military and consumer market. The instrumentation amplifier is ideal for use in instrumentation systems for temperature, pressure, speed and vibration monitoring. It is also used in laboratory and industrial applications for audio signal measurement, bio-signal conditioning, electrochemical and biosensor signal conditioning. The amplifier can also be used in mobile communications and sensing applications.

The AD8698ARMZ-REEL is also used for process control and monitoring in industrial and commercial applications. With its wide input common mode range, it can be used with either single or dual power supplies and it has a high common-mode rejection ratio to handle noise sources. The open-loop gain and adjustable gain bandwidth make the amplifier suitable for both AC and DC signal conditioning applications.

Working Principle

The AD8698ARMZ-REEL operates as an instrumentation amplifier using two high-precision operational amplifiers. The two operational amplifiers, when combined, create an amplifier with very low noise and offset voltage, as well as high common-mode rejection. The difference signal (output signal) is produced by subtracting the input signals of both amplifiers (inverting and non-inverting) and then amplifying the resulting signal. The difference signal is then amplified by the main amplifier to the desired output signal level.

The gain of the AD8698ARMZ-REEL instrumentation amplifier is adjustable, allowing it to be used in both single and dual configurations. In single configuration, the gain of the amplifier is adjusted using a single resistor. In dual configuration, two resistors are used to adjust both the relative gains of the two amplifiers. A feedback resistor is also provided in order to control the maximum amplifier gain and precise control of the output gain.

Conclusion

The AD8698ARMZ-REEL is a precision instrumentation amplifier with a range of applications. It is used in medical, industrial and consumer markets for signal measurement and conditioning. It has adjustable gain, wide input common mode range and high common-mode rejection ratio. The amplifier has low noise, offset voltage, and is capable of operating in both single and dual configurations.
