LME49870 44V Single High Performance, High Fidelity Audio Operational Amplifier www.DataSheet4U.com January 14, 2008 LME49870 44V Single High Performance, High Fidelity Audio Operational Amplifier General Description The LME49870 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. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49870 audio operational amplifier delivers superior audio signal amplification for outstanding audio performance. The LME49870 combines extremely low voltage noise density (2.7nV/√Hz) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49870 has a high slew rate of ±20V/μs and an output current capability of ±26mA. 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 LME49870's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance. The LME49870 has a wide supply range of ±2.5V to ±22V. Over this supply range the LME49870 maintains excellent common-mode rejection, power supply rejection, and low input bias current. The LME49870 is unity gain stable.
