Evaluation Board License Agreement

Quad High Performance, High Fidelity Audio Operational Amplifier

LME4940 Product Folder

Device Description:

The LME49740 is a Quad High Fidelity Audio Operational Amplifier. This Audio Amplifier offers near zero THD+N and sets a new

standard for high end audio users. Nationals newest Amplifier uses state of the art circuitry and process to achieve a new class

of audio performance and technology. The AC and DC parameters in this amplifier series offers users a solution well suited for the

most demanding signal path applications. There are two package choices to enable all users ease of use and evaluation criteria.

The LME49740 is designed for high slew rate, low noise and high output for systems needing +/-2.5 to +/-17V functionality.

The pin out is the National standard to quickly upgrade existing boards. This series is for applications such as high quality audio

amplification, multi-media, imaging, line drivers/receivers and active filters. The output current is for 600Ohm loads with more

than 26mA drive with THD+N over a wide voltage range.

The LME49740MABD and LME49740NABD are evaluation boards designed to establish performance and evaluation to design the

best end user system. The evaluation boards include all components for a ready-to-use, stand-alone bench work.
