www.ti.com SNOSAD2G – MAY 2004 – REVISED MARCH 2013 LMH6739 Very Wideband, Low Distortion Triple Video Buffer
Check for Samples: LMH6739 FEATURES 1 2 DESCRIPTION 750 MHz -3 dB small signal bandwidth
(AV = +1)
-85 dBc 3rd harmonic distortion (20 MHz)
2.3 nV/в€љHz input noise voltage
3300 V/Ојs slew rate
32 mA supply current (10.6 mA per op amp)
90 mA linear output current
0.02/0.01 Diff. Gain/ Diff. Phase (RL = 150Ω)
2mA shutdown current The LMH6739 is a very wideband, DC coupled
monolithic selectable gain buffer designed specifically
for ultra high resolution video systems as well as wide
dynamic range systems requiring exceptional signal
fidelity. Benefiting from current feedback architecture,
the LMH6739 offers gains of -1, 1 and 2. At a gain of
+2 the LMH6739 supports ultra high resolution video
systems with a 400 MHz 2 VPP3 dB Bandwidth. With
12-bit distortion level through 30 MHz (RL = 100Ω),
2.3nV/в€љHz input referred noise, the LMH6739 is the
ideal driver or buffer for high speed flash A/D and D/A
converters. Wide dynamic range systems such as
radar and communication receivers requiring a …
