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 operational amplifiers deliver superior audio signal amplification
for outstanding audio performance. The LME49723
combines extremely low voltage noise density
(3.6nV/√Hz) with vanishingly low THD+N (0.0002%)
to easily satisfy the most demanding audio
applications. To ensure that the most challenging
loads are driven without compromise, the LME49723
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 LME49723's outstanding CMRR (100dB), PSRR
(100dB), and VOS (0.3mV) give the amplifier excellent
operational amplifier DC performance.
The LME49723 has a wide supply range of ±2.5V to
±17V. Over this supply range the LME49723’s input
circuitry maintains 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 package. Demonstration boards are available
for each package.
