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 feature­rich, high value video portfolio to include a dual and a triple version. The important video specifications of differential
±
gain ( 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 Semicon­ductor’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 2kload. 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 MSOP-8. The LMH6683 triple amplifier is offered in SOIC-14 and TSSOP-
14.
