Overview

The LME49720NA is a high-performance, ultra-low distortion dual audio operational amplifier designed for high-fidelity signal paths. It features a wide supply range from 2.5V to 17V and a high slew rate of 20V/us, making it suitable for professional audio applications requiring superior signal integrity.

Why Choose This Part

This amplifier offers an exceptionally low noise density of 2.7 nV/rtHz and a high gain bandwidth of 55 MHz for transparent audio reproduction. Its 8-DIP package is ideal for through-hole prototyping or upgrading existing audio equipment sockets.

Applications

Professional Audio Preamplifiers
Ideal for low-noise front-ends in mixing consoles and recording interfaces.
High-Fidelity Active Filters
High gain bandwidth product of 55 MHz allows for precise active crossover and equalization designs.
Line Drivers
Capable of driving complex loads in high-end consumer and professional audio distribution.
Phono Preamp Stages
The ultra-low noise floor and 100 uV offset voltage are critical for amplifying sensitive analog signals.
