Introduction: The MAX4247AUB+T is a complete instrumentation amplifier (IA) and buffer amplifier offering unparalleled mixture of performance, size, and cost savings. With the goal of maintaining improvement in size reduction, low-power consumption, high performance, wide linearity, and high accuracy, the MAX4247AUB+T has been designed to achieve maximum performance without compromising any of these above factors. It is an ideal instrumentation amplifier for low-power, precision signal conditioning over a wide range of applications.

Description: The MAX4247AUB+T combines the features of an instrumentation amplifier with a buffer amplifier in one integrated circuit, saving substantially on footprint and component costs. The instrumentation amplifier component of the MAX4247AUB+T offers a low-power, high-linearity solution for low-frequency and wideband applications. With its low-noise, low-power consumption, high-speed, and wide linearity, it can be used to achieve wide bandwidths, such as low-frequency low-noise applications. The instrumentation amplifier component can be used with either one or two different differential inputs.

Features: The MAX4247AUB+T offers a wide range of features including low power consumption, low-noise input, wide linearity, wide operating temperature ranges, differential input capability, temperature stability, and low-cost packaging. The MAX4247AUB+T also includes a unity gain differential buffer amplifier for buffering and driving low impedance load.

Applications: The MAX4247AUB+T is ideal for applications such as sensor signal conditioning, audio signal conditioning, test and measurement systems, low-frequency signal amplification, wideband signal conditioning, and many others. Furthermore, its wide operating temperature range, low-noise input, wide linearity, and low distortion make it suitable for noise-sensitive systems, such as medical instrumentation amplifiers, where absolute accuracy and excellent dynamic performance are required.

Working Principles: The MAX4247AUB+T has two differential amplifiers. The first amplifier is an accurate, precision differential amplifier whose gain is controlled by two feedback resistors. The second amplifier is a buffer amplifier. This amplifier provides high speed, low-noise buffering of the differential signal. The buffer amplifier is enabled by two input signals, a reset signal and an enable signal. If the reset signal is asserted, the input signals are buffered with a gain of unity (-1). When the enable signal is asserted, the buffer amplifier\'s gain increases to four times the input voltage.

Conclusion: The MAX4247AUB+T is a complete instrumentation amplifier and buffer amplifier offering unparalleled mixture of performance, size, and cost savings. With its low-power, high-linearity solution, wide operating temperature range, low-noise input, and wide linearity, the MAX4247AUB+T is ideal for low-power, precision signal conditioning. The MAX4247AUB+T is applicable to a wide range of applications including sensor signal conditioning, audio signal conditioning, test and measurement systems, low-frequency signal amplification, and many others.
