DESCRIPTION
The LME49713 is an ultra-low distortion, low noise,
ultra high slew rate current feedback 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 LME49713 current
feedback operational amplifier delivers superior signal
amplification for outstanding performance. Operating
on a wide supply range of ±5V to ±18V, the
LME49713 combines extremely low voltage noise
density (1.9nV/√Hz) with very low THD+N (0.00036%)
to easily satisfy the most demanding applications. To
ensure that the most challenging loads are driven
without compromise, the LME49713 has a high slew
rate of ±1900V/μs and an output current capability of
±100mA. Further, dynamic range is maximized by an
output stage that drives 150Ω loads to within 2.9V of
either power supply voltage.
The LME49713's outstanding CMRR (88dB), PSRR
(100dB), and V_OS (0.05mV) give the amplifier
excellent operational amplifier DC performance.
The LME49713 is available in an 8-lead narrow body
SOIC and an 8-lead TO-99. Demonstration boards
are available.
