LMP7731MFE/NOPB

The LM7731MFE/NOPB is a high-performance, low-noise power amplifier designed for a wide variety of applications. Its features and performance make it ideal for low-noise preamplification, high-level medical and portable electronics, and test and measurement gain stages. It is also used in instrumentation and data acquisition systems.

The LM7731MFE is a monolithic integrated bipolar linear device that operates from ±10V or a single 5V power supply. It offers both an adjustable gain range of 0 - 140dB, and an adjustable cutoff frequency of 0 - 6.5kHz. The amplifier offers 100dB of gain at 3kHz with a power bandwidth of 5MHz, high slew rate, low noise, and low input bias current.

The LM7731MFE is available in both single and dual supply versions. In the single supply version, the output voltage is restricted by a single power supply. The dual supply version offers the same performance but with an output voltage that is free to range on either side of the power supply.

The LM7731MFE is an ideal amplifier for instrumentation and data acquisition systems due to its low noise, high gain, wide speed, and low input bias current. This device also offers excellent isolation, excellent output drive capability, and input voltage noise immunity. Additionally, this device is ideal for applications requiring low noise preamplification, such as medical, audiophile, and portable electronics, and test and measurement gain stages.

The amplifier’s working principle involves the use of a differential input stage. This is a key feature of the LM7731MFE and is necessary for high-performance gains. The amplifier also utilizes a current feedback topology, which allows for adjustable gain of 0 - 140dB. Additionally, the amplifier offers adjustable cutoff frequency of 0 - 6.5kHz, with a power bandwidth of 5MHz, resulting in excellent isolation and accuracy.

The LM7731MFE/NOPB is ideal for many applications and components requiring high-performance and low-noise operations. As such, it can be used in many fields such as in medical and portable electronics, audiophile systems, and test and measurement gain stages. The device also offers excellent isolation and low electric input noise, making it ideal for instrumentation and data acquisition systems.
