DESCRIPTION
The LMH6682 and LMH6683 are high speed
operational amplifiers designed for use in modern
video systems. These single supply monolithic
amplifiers extend TI's feature-rich, high value video
portfolio to include a dual and a triple version. The
important video specifications of differential gain (±
0.01% typ.) and differential phase (±0.08 degrees)
combined with an output drive current in each
amplifier of 85mA make the LMH6682 and LMH6683
excellent choices for a full range of video
applications.
Voltage feedback topology in operational amplifiers
assures maximum flexibility and ease of use in high
speed amplifier designs. The LMH6682/83 is
fabricated in TI's VIP10 process. This advanced
process provides a superior ratio of speed to
quiescient current consumption and assures the user
of high-value amplifier designs. Advanced technology
and circuit design enables in these amplifiers a −3db
bandwidth of 190MHz, a slew rate of 940V/μsec, and
stability for gains of less than −1 and greater than +2.
The input stage design of the LM6682/83 enables an
input signal range that extends below the negative
rail. The output stage voltage range reaches to within
0.8V of either rail when driving a 2kΩ load. Other
attractive features include fast settling and low
distortion. Other applications for these amplifiers
include servo control designs. These applications are
sensitive to amplifiers that exhibit phase reversal
when the inputs exceed the rated voltage range. The
LMH6682/83 amplifiers are designed to be immune to
phase reversal when the specified input range is
exceeded. See applications section. This feature
makes for design simplicity and flexibility in many
industrial applications.
The LMH6682 dual operational amplifier is offered in
miniature surface mount packages, SOIC-8, and
VSSOP-8. The LMH6683 triple amplifier is offered in
SOIC-14 and TSSOP-14.
