MAX4168ESD is a precision, micropower operational amplifier that can be used as a unity-gain buffer amplifier. It offers a combination of low noise, high accuracy and low-power operation, making it suitable for a variety of instrumentation and signal conditioning applications. The device is designed to provide a high-impedance gateway for signals in and out of a system, and its low-power architecture ensures a minimal effect on data integrity and accuracy.

The MAX4168ESD can be driven from a variety of power sources and needs only 4.5V to 5.5V for highly accurate signal conditioning for applications that do not require a high output current. The device offers over 120 dB signal-to-noise ratio, which has mistakenly been thought of as being a signal-to-noise ratio of A-weighted signals. The MAX4168ESD has a wide common-mode input voltage range of ±12V, and it can be used in a split power supply configuration with a fully differential signal range of ±3.3V.

The MAX4168ESD can be used as a stand-alone amplifier or, with several cascaded amplifiers, create an array of image-conditioning signals for polarimetry, photoluminescence, and fluorescence imaging systems. Some of these imaging systems are used for analysis of spectroscopic data to separate and quantify samples from solid, liquid, and gaseous sources. The MAX4168ESD also allows for accurate, low power interfacing with A/D converters and other digital circuitry. Particular attention has been paid to the design of the output stage, as it must meet stringent requirements for low noise, fast response and low quiescent power.

The MAX4168ESD’s typical high slew rate (300V/μs) and low distortion make it ideal for use in applications across a broad range of frequencies, including audio. This device features low High-Power-Mode distortion, meaning that it won’t introduce high levels of distortion when working with high source impedances. In addition, because this device has an open-loop input impedance of over 10GΩ, it can be used in a wide range of interconnect applications without adversely affecting the signal.

The MAX4168ESD provides a unity-gain stable frequency response and low output noise, making it suitable for low-level signal-conditioning in both control loop systems and laboratory instrumentation circuits. It is also optimal for applications where low offset, low noise and low power consumption are critical. The device integrates two input-to-output amplifiers to provide functionally identical performance for double-ended or single-ended operation. In addition, due to its power-saving design and superior circuitry, the MAX4168ESD has a very low quiescent current of only 0.001uA. Furthermore, the power consumption in the “On” mode is only 2.5mA.

In summary, the MAX4168ESD operational amplifier is a great device for low noise, high performance, low power applications. By taking advantage of the incredibly low power consumption of the amplifier, the MAX4168ESD is perfect for applications like measurement, automation, and control equipment. Its fast response time and low offset make this device ideal for a variety of instrumentation and signal conditioning applications, ranging from low-level audio conditioning to data acquisition and processing.
