LME49723 is an ultra-low distortion, low-noise, high-conversion rate operational amplifier series, offering high performance and high fidelity applications, fully optimized and specified as part of the market. Combined with the nation's most advanced circuit design and cutting-edge process technology, LME49723 audio operational amplifiers deliver excellent audio performance and superior audio signal amplification. LME49723 combined with an extremely low voltage-to-noise density (3.6nV / √^hertz) and an extremely low THD + N (0.0002%), it easily meets the demands of the most demanding audio applications. To ensure the most challenging loads are uncompromised drives, LME49723 features a high voltage swing rate of ±20V/μs and a ±26mAh output current capability. Additionally, to maximize dynamic range, the output stage drives 600Ω loads within 1V and 1.4V of any supply voltage within the 2kΩ load range. LME49723 excellent CMRR (100 dB), (PSRR100 dB), and V OS (0.3mV) amplifiers provide excellent operational amplifier DC performance. LME49723 has a wide power supply voltage range from ± 2.5V to ± 17V. LME49723 input circuit, maintaining excellent common-mode and power suppression within this supply voltage range, as well as maintaining low input bias current. LME49723 is stable gain per unit. LME49723 is a narrow-body SOIC with 8 pins. Each package presents a board.
