LMH6739
Very Wideband, Low Distortion Triple Video Buffer
General Description
The LMH6739 is a very wideband, DC coupled monolithic se-
lectable gain buffer designed specifically for ultra high reso-
lution video systems as well as wide dynamic range systems
requiring exceptional signal fidelity. Benefiting from National's
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 V
3 dB Bandwidth. With 12-bit distortion level through 30 MHz
(R
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 wideband amplifier of-
fering exceptional signal purity will find the LMH6739’s low
input referred noise and low harmonic distortion make it an
attractive solution. The LMH6739 is offered in a space saving
SSOP package.
