The device is also designed to scale well with increased requirements.

Application Field of LMV722M/NOPB

The LMV722M/NOPB\'s wide range of flexibility and performance enables it to be used in a variety of applications from instrumentation systems to portable audio devices. It is suitable for data acquisition systems, precision and low power audio amplifiers, fast A/D converters and active filter circuits. Due to its wide input common mode differential gain and high output current drive, it is also well-suited to non-inverting amplifiers, active filters, differential bridges, smoothing circuits, AGC, and transmission line balancing.

Working Principle of LMV722M/NOPB

The LMV722M/NOPB consists of two stages: an input stage, where sound signals are converted into electrical signals, and an output stage, where the electrical signals are amplified. The input stage employs one of the two types of transistors. The first type is MOSFET, which stands for "Metal-Oxide-Semiconductor Field-Effect Transistor." MOSFET is chosen typically for its low input bias current and low offset. The second type is CMOS, which stands for "Complementary-Metal-Oxide-Semiconductor." CMOS is chosen for its low power consumption and high noise immunity.

The output stage is comprised of a Class AB output stage for low distortion, high power output, and low-noise. This enables the LMV722M/NOPB to be used in high gain applications such as active filter circuits, or low noise applications such as A/D converters. The device is also designed with a 9mA output current capability and a wide output swing of 16.5V. It also features an offset trim pin to achieve a gain accuracy of 0.001%.
