DESCRIPTION

· The LMH6739 is a very wideband, DC coupled monolithic selectable gain buffer designed for ultra-high resolution video systems and wide dynamic range systems requiring exceptional signal fidelity.

· It benefits from current feedback architecture, offering gains of -1, 1, and 2, supporting ultra-high resolution video systems with a 400MHz 2VPP 3dB bandwidth at a gain of +2.

· With 12-bit distortion level through 30MHz (RL=100Ω) and 2.3nV/√Hz input referred noise, it is ideal for driving or buffering high-speed flash A/D and D/A converters.

FEATURES

· 750MHz -3dB small signal bandwidth (AV=+1).

· -85dBc 3rd harmonic distortion at 20MHz.

· 2.3nV/√Hz input noise voltage.

· 3300V/μs slew rate.

· 32mA supply current (10.6mA per op amp).

· 90mA linear output current.

· 0.02/0.01 Diff. Gain/Diff. Phase (RL=150Ω).

· 2mA shutdown current.

· RGB video driver.

· High resolution projectors.

· Flash A/D driver.

· D/A transimpedance buffer.

· Wide dynamic range IF amplifier.

· Radar/communication receivers.

· DDS post-amps.

· Wideband inverting summer.

· Line driver.
