In terms of working principle, LMV844MA/NOPB is an instrumentation amplifier which works with an input differential gain stage, an output differential amplifier and a high performance operational amplifier. The input differential gain stage receives a differential input signal and amplifies it fully differential with a gain A before it is sent to the output differential amplifier. The output differential amplifier then amplifies the signal before it is sent to the operational amplifier for further gain control. LMV844MA/NOPB also incorporates an active output stage which provides an increased output range and polarity reversal. This active output stage also provides a low power efficiency and a high dynamic range.

The LMV844MA/NOPB is an ideal low-noise amplifier for applications requiring high-performance, precise gain control and excellent noise performance. It is ideal for data acquisition and communication systems, medical imaging systems and high performance audio systems, among other applications. It is designed to deliver excellent low-frequency and high-frequency performance, fast settling time, low distortion and low-power consumption. The amplifier is designed to operate over a wide frequency range, with wide gain control range and wide input/output common-mode range.
