The LMH6682 and LMH6683 are high-speed operational amplifiers designed with modern video systems. These single-supply powered monolithic amplifiers extend the country's feature-rich, high value-added video products, including dual and triple versions. Important video specifications, differential gain (typical± 0.01%) and differential phase are an excellent choice for the LMH6682 and LMH6683 full range of video applications that combine the output drive current of each 85 mA amplifier (± 0.08 degrees).
The topology of the voltage feedback op amp guarantees maximum flexibility and ease of use in the design of high-speed amplifiers. LMH6682/83 is a VIP10 process technology manufacturing of National Semiconductor. This advanced process provides a superior speed over Quiescient current consumption, guaranteeing users a high value amplifier design. Advanced technology and circuit design enable the stability of these amplifiers with a -3dB bandwidth of 190MHz and a slew rate of 940V/μsec, less than -1 to 2.
The LM6682/83 input stage design extends the input signal range below the negative rail. The output stage voltage range reaches 0.8V or 2K when traveling on railways Load. Other attractive features include fast stabilization and low distortion. Other applications for these amplifiers include servo control designs. These applications are sensitive to amplifiers that exhibit phase reversal when the input exceeds the rated voltage range. The LMH6682/83 amplifiers are designed to invert the immune phase when the specified input range is exceeded. See the Applications section. This feature makes for simplicity and flexibility in design in many industrial applications.
The LMH6682 dual op amp is available in a miniature surface mount package in SOIC-8 and MSOP-8. The LMH6683 triple amplifier is available in SOIC-14 and TSSOP-14.
