LME49710 High Performance, High Fidelity Audio Operational Amplifier
General Description
The LME49710 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 LME49710 audio operational
amplifiers deliver superior audio signal amplification for
outstanding audio performance. The LME49710 combines
extremely low voltage noise density (2.5nV/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
LME49710 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 LME49710's outstanding CMRR(120dB), PSRR(120dB),
and VOS (0.05mV) give the amplifier excellent operational
amplifier DC performance.
The LME49710 has a wide supply range of ±2.5V to ±17V.
Over this supply range the LME49710’s input circuitry maintains
excellent common-mode and power supply rejection, as
well as maintaining its low input bias current. The LME49710
is unity gain stable. The Audio Operational Amplifier achieves
outstanding AC performance while driving complex loads with
values as high as 100pF.
The LME49710 is available in 8–lead narrow body SOIC, 8–
lead plastic DIP, and 8–lead metal can TO-99. Demonstration
boards are available for each package.
