LME49723
LME49723 is Dual High Fidelity Audio Operational Amplifier manufactured by National Semiconductor.
Description
The LME49723 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity applications. bining advanced leading-edge process technology with state-of-the-art circuit design, the LME49723 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LME49723 bines .. extremely low voltage noise density (3.6n V/√Hz) with vanishingly low THD+N (0.0002%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without promise, the LME49723 has a high slew rate of ±20V/μs and an output current capability of ±26m A. Further, dynamic range is maximized by an output stage that drives 2kΩ loads to within 1V of either power supply voltage and to within 1.4V when driving 600Ω loads. The LME49723's outstanding CMRR (100d B), PSRR (100d B), and VOS (0.3m V) give the amplifier excellent operational amplifier DC performance. The LME49723 has a wide supply range of ±2.5V to ±17V. Over this supply range the LME49723’s input circuitry maintains excellent mon-mode and power supply rejection, as well as maintaining its low input bias current. The LME49723 is unity gain stable. The LME49723 is available in an 8- lead narrow body SOIC. Demonstration boards are available for each package.
