LMH6682/6683
190MHz Single Supply, Dual and Triple Operational
Amplifiers
General Description
The LMH6682 and LMH6683 are high speed operational
amplifiers designed for use in modern video systems. These
single supply monolithic amplifiers extend National’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 National Semicon-
ductor’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. Ad-
vanced technology and circuit design enables in these am-
plifiers 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 2k
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 applica-
tions section. This feature makes for design simplicity and
flexibility in many industrial applications.
The LMH6682 dual operational amplifier is offered in minia-
ture surface mount packages, SOIC-8, and MSOP-8. The
LMH6683 triple amplifier is offered in SOIC-14 and TSSOP-
14.
