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.
