AD8639WARZ-RL

The AD8639WARZ-RL is an instrumentation amplifier, or in-amp, that is part of the Analog Devices line of high precision linear amplifiers. These class of amplifiers have gained a lot of popularity due to their ability to magnify tiny, low-level differential signals. The AD 8639WARZ-RL is a long-proven design that was produced to precision, low noise, and low power specifications.

Applications

The AD8639WARZ-RL is a general purpose in-amp that can be used in many different applications. It is an ideal choice when operating at low noise, low gain and low power levels. It can be used in many different areas, including medical, consumer, automotive and telecommunications. Some of its most common applications are:

• Safety critical measurements (medical, automotive and consumer applications)
• Measuring vibration and noise levels
• Measuring magnetic field strength
• Measuring thermal values and temperature

Benefits

The AD8639WARZ-RL is an ideal in-amp for applications needing low noise and low power levels. It offers many benefits, such as higher CMR and CMRR than other in-amps, as well as low current consumption. It can also be easily configured through several selectable gain ranges.

Working Principle

The AD8639WARZ-RL is a differential amplifier and is one of the few that has high CMR and CMRR ratings. It works by amplifying the difference between two input signals, while simultaneously rejecting unwanted electrical signals or noise. The in-amp utilizes a differential amplifier with an active gain stage. This stage is driven by an input buffer which provides a constant current/voltage source. The output of the first amplifier is then applied to the second differential amplifier, which acts as an output buffer. This allows the amplifier to achieve a higher gain or common mode rejection ratio.

Conclusion

The AD8639WARZ-RL is a versatile and reliable instrumentation amplifier which is suitable for many applications. It can provide excellent performance in areas such as medical, consumer, automotive, and telecommunications. It is also great for measuring small differential signals, due to its high CMR and CMRR ratings. With its low power and noise levels, it is a great choice for applications where precision and versatility are needed.
