Working Principle

The LM49250RLX/NOPB is a fully differential amplifier with a differential input impedance of 600Ω and a wide -20dB bandwidth of 3 kHz. It is designed to amplify signals along two input channels simultaneously, resulting in both low noise and very accurate results. The differential gain is controlled by changing the ratio of the two input resistors.

The LM49250RLX/NOPB features a high input voltage swing (14V peak-to-peak), which allows it to provide maximum linearity and low noise. It also features an adjustable current feedback (ACF) configuration, which makes it possible to adjust the amplifier gain without having to resort to gain potentiometers.

The LM49250RLX/NOPB is designed to minimize distortion by using a dynamic compensation circuit. This circuit controls the compensation parameters of the amplifier to ensure low distortion even at high signal levels. The LM49250RLX/NOPB also has a low signal to noise ratio of 80dB, making it suitable for both sensitive and noisy environments.
