The LME49723 is fully optimized and specified for ultra-low distortion, low noise, high slew rate operational amplifier family, high performance, high fidelity applications. Combined with state-of-the-art circuit design and cutting-edge process technology, the LME49723 audio operational amplifier provides superior audio performance and superior audio signal amplification. The LME49723 combines extremely low voltage noise density (3.6nV/√^Hz) with a minimally low THD+N (0.0002%) to easily meet the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49723 has a high slew rate of ±20V/μs and an output current capability of ±26 mA. In addition, dynamic range is maximized when driving an output stage within 1V and 1.4V of either supply voltage within a 2kΩ load range. The LME49723's excellent CMRR (100 dB), (PSRR100 dB) and V OS (0.3mV) amplifiers have excellent op amp DC performance. The LME49723 has a wide supply voltage range of ± 2.5V to ± 17V. The input circuitry of the LME49723 maintains excellent common-mode and power supply rejection over this supply voltage range, as well as its low input bias current. The LME49723 is unity-gain stable. The LME49723 is an 8-pin narrow body SOIC. Demo board for each package.
