LME49723
Dual High Fidelity Audio Operational Amplifier
General Description
The LME49723 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 LME49723 audio opera-
tional amplifiers deliver superior audio signal amplification for
outstanding audio performance. The LME49723 combines
extremely low voltage noise density (3.6nV/
ishingly low THD+N (0.0002%) to easily satisfy the most
demanding audio applications. To ensure that the most chal-
lenging loads are driven without compromise, the LME49723
has a high slew rate of ±20V/μs and an output current capa-
bility 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 LME49723's outstanding CMRR (100dB), PSRR
(100dB), and V
ational amplifier DC performance.
The LME49723 has a wide supply range of ±2.5V to ±17V.
Over this supply range the LME49723’s input circuitry main-
tains excellent common-mode and power supply rejection, as
well as maintaining its low input bias current. The LME49723
is unity gain stable.
The LME49723 is available in an 8–lead narrow body SOIC.
Demonstration boards are available for each package.
