Linear Amplifiers

The LMH6601QMGX/NOPB is ideal for use in linear amplifier systems. With high operating speed and low input referred noise levels, it is well suited for demanding applications such as TV/video amplifiers, high speed data converters, and differential preamplifiers. The low-distortion architecture allows for high signal-to-noise ratios and high linearity, providing superior performance even in very noisy environments. The high input impedance allows it to drive long lines with minimal insertion loss.

Instrumentation

The LMH6601QMGX/NOPB is also a popular choice for instrumentation applications. Its low-noise amplifier characteristics, high-speed operation, and wide common-mode voltage range make it well suited for controlling sensitive signals. It is commonly used in laboratory and industrial systems, such as data acquisition systems and signal conditioners. It can also be used in digital voltmeters, programmable logic controllers, and low-distortion audio applications.

Op-Amps

In addition to the aforementioned use cases, the LMH6601QMGX/NOPB is frequently deployed as an operational amplifier. With high gain bandwidths and low offset voltages, it is particularly well-suited for closed-loop control applications such as precision voltage-to-current converters and high speed anti-aliasing filters. It can also be used in applications like active filters and audio systems, due to its low harmonic distortion and wide dynamic range.

Buffer Amps

The LMH6601QMGX/NOPB is also well suited for buffer amplifier applications. Its wide bandwidth and high slew rate enable it to drive capacitive loads and provide fast recovery times. Its high input impedance and wide operational voltage range make it ideal for driving high-speed digital signals as well. The low noise levels and low differential gain/phase allow it to be used in a wide variety of signal integrity applications.

Working Principle

The LMH6601QMGX/NOPB is a fully differential-input amplifier that uses a current-feedback architecture. The input signal is divided into two equal parts and the voltage signal generated is fed into two current-mirror channels. The channel outputs are then recombined to produce a fully differential output. This architecture allows for high input impedance, low input referred noise, and a wideband, low-distortion signal gain. In this configuration, the input signals are untouched and only the magnitude and phase are modified.

The LMH6601QMGX/NOPB is capable of a wide range of gains, making it effective in most applications. It features excellent input referred noise, low harmonic distortion, low input voltage offset, and low gain error. Additionally, it can be configured in the usual series-parallel manner, with one amplifier driving the other, allowing for rapid changes of the gain. All of these characteristics make it a superior choice for a variety of linear, instrumentation, operational amplifier, and buffer amplifier applications.

In conclusion, the LMH6601QMGX/NOPB is an ideal choice for applications requiring high operating speed and low input referred noise levels. With its wide range of gains, low harmonic distortion and noise levels, low input voltage offset, and low gain error, this amplifier is a versatile and reliable choice for many applications in the linear, instrumentation, operational amplifier, and buffer amplifier fields.
