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 150
Ω loads to within 2.9V of either
power supply voltage.
The LME49713 's outstanding CMRR (88dB), PSRR (100dB), and VOS (0.05mV) give the amplifier excellent
operational amplifier DC performance.
The LME49713 is available in an 8–lead narrow body SOIC and 8–lead metal can (TO-99). Demonstration
boards are available.
