The LM7321QMFX/NOPB is an analog linear amplifier incorporating a single rail-to-rail output stage, high supply voltage and low quiescent current. This device offers many options for the user, including programmable gain, low power consumption and excellent performance, making it suitable for a variety of applications such as instrumentation, data acquisition and buffering.

The LM7321QMFX/NOPB is also a low noise, low distortion and low offset amplifier, ensuring precision and reliable operation in a wide variety of audio, medical, industrial and other application areas.

The LM7321QMFX/NOPB’s intrinsic features that make it highly desirable for an application field and effective performance is enabled by its solid design, using a combination of parts from a wide range of product lines to provide a flexible and cost-effective solution. This device is designed for a single 5 V or 3 V supply operation, but the internal circuitry may be widely used for both supplies.

The LM7321QMFX/NOPB typically has a single ended input stage with a cascode output stage, depending on the amplitude and setting of the feedback resistor. The feedback resistor sets the gain of the amplifier, which is typically symmetrical between the inverting (Vin-) and the non-inverting (Vin+) pins, respectively. The device\'s gain is proportional to the feedback resistor (Rf), which is set either externally or internally by the user depending on the application. The unity gain bandwidth is generally higher than 1MHz and slew rate is typically 280V/µs.

The circuitry of the LM7321QMFX/NOPB is also designed to increase thermal stability, reduce noise and protect against any ESD damage. The internal circuitry incorporates an over-voltage protection system that enables the user to protect against transient voltages, as well as parasitic transients. Additionally, the device includes an ESD protected output stage, which enables the user to protect against unwanted transient voltage surges, helping to increase the lifetime of the device.

The LM7321QMFX/NOPB has excellent features including low-noise (1.3nV/√Hz) and low-distortion (0.03%) amplifiers, both of which leverage the Rail-to-Rail output stage to provide the user with excellent accuracy and control. Furthermore, this amplifier also features a high input impedance (1.2MΩ) which ensures robust performance and reliable operation in a variety of application areas.

In summary, the LM7321QMFX/NOPB is an excellent product for a range of linear instrumentation applications such as amplification, signal processing, data acquisition, buffering and more. Its combination of features make it an ideal choice for a broad range of applications while its small size, low power consumption and robustness make the product particularly suitable for high-tech and demanding environments.
