The LM4565FVJ-GE2 is an instrumentation amplifier, designed for high precision applications in the audio and measurement domain. It is a fully-differential amplifier offering high CMRR, high precision and low power. It provides low distortion, low noise and a wide range of input common-mode range. It offers high linearity, maximum gain accuracy and excellent dynamic performance.

The LM4565FVJ-GE2 consists of two gain stages and two input stages. The first stage is a unity-gain instrumentation amplifier consisting of two difference amplifiers and two gain stages (large-signal and small-signal). The differential input stage provides high CMRR and low common mode offset voltage. The large-signal stage amplifies the input signal by a factor dependent on the gain setting. The small-signal stage provides gain matching for the large-signal stage and also provides very low offset voltage and very low input bias current.

The second stage is a complementary-symmetry differential output stage. This stage provides high power output and high voltage gain. The rail-to-rail capability of the output stage allows full utilization of the dynamic range of the device.

The LM4565FVJ-GE2 is ideal for medical, scientific, and other precision applications requiring high precision and dynamic precision. Its low noise and low power capabilities makes it suitable for portable equipment such as wireless microphones. The excellent common-mode rejection ratio (CMRR) ensures that only the desired signals are amplified while rejecting unwanted noise.

The LM4565FVJ-GE2 is also suitable for high performance audio applications such as professional mixing consoles and modern audio products. Its low distortion and excellent noise performance can help reduce audible artifacts due to amp noise and distortion.

The wide range of gain settings allows for a variety of applications, from low-level signals to high-level signals. The gain can be adjusted from unity gain up to a maximum of 20 dB. The amplifier can be driven from low impedance sources using a low power supply, and is capacitor-free for reduced component count.

The LM4565FVJ-GE2 is a versatile instrumentation amplifier that is suitable for a variety of precision applications. Its excellent gain accuracy, wide input common-mode range, low noise, low distortion and high power capability make it an ideal choice for high performance applications.
