The LME49724 is an ultra-low distortion, low noise, high slew rate fully-differential
operational amplifier optimized and fully specified for high performance, high fidelity
applications. Combining advanced leading-edge process technology with state of the art circuit
design, the LME49724 fully-differential audio operational amplifier delivers superior audio signal
amplification for outstanding audio performance. The LME49724 combines extremely low voltage noise
density (2.1nV/√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 LME49724 has a high slew rate of ±18V/μs and an output current capability of ±80mA.
Further, dynamic range is maximized by an output stage that drives 600Ω loads to
52VP-P while operating on a ±15V supply voltage.
The LME49724's outstanding CMRR (102dB), PSRR (125dB), and VOS
(0.2mV) results in excellent operational amplifier DC performance.
The LME49724 has a wide supply range of ±2.5V to ±18V. Over this supply range the
LME49724’s input circuitry maintains excellent common-mode and power supply rejection, as well as
maintaining its low input bias current. The LME49724 is unity gain stable. This Fully-Differential
Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with
capacitive values as high as 100pF.
