include servo control designs. These applications are

sensitive to amplifiers that exhibit phase reversal

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.

LMH6682, LMH6683 SNOSA43A – MAY 2004 – REVISED APRIL 2013 www.ti.com APPLICATIONS SECTION LARGE SIGNAL BEHAVIOR Amplifying high frequency signals with large amplitudes (as in video applications) has some special aspects to look after. The bandwidth of the Op Amp for large amplitudes is less than the small signal bandwidth because of slew rate limitations. While amplifying pulse shaped signals the slew rate properties of the OpAmp become more important at higher amplitude ranges.

LMH6682, LMH6683 www.ti.com SNOSA43A – MAY 2004 – REVISED APRIL 2013 Figure 52. This property of the LMH6682/83 guaranties a higher slew rate at higher differential input voltages. ΔV/Δt = ΔV*Gm/C (5) In Figure 53 one can see that a higher transient voltage than will lead to a higher slew rate. Figure 53. HANDLING VIDEO SIGNALS When handling video signals, two aspects are very important especially when cascading amplifiers in a NTSC- or PAL video system.

LMH6682, LMH6683 SNOSA43A – MAY 2004 – REVISED APRIL 2013 www.ti.com OUTPUT PHASE REVERSAL This is a problem with some operational amplifiers. This effect is caused by phase reversal in the input stage due to saturation of one or more of the transistors when the inputs exceed the normal expected range of voltages. Some applications, such as servo control loops among others, are sensitive to this kind of behavior and would need special safeguards to ensure proper functioning.

LMH6682, LMH6683 www.ti.com SNOSA43A – MAY 2004 – REVISED APRIL 2013 Figure 54. In Figure 54 it can be seen that there's more peaking with higher resistor values, which can lead to oscillations and bad pulse responses. On the other hand the low resistor values will contribute to higher overall power consumption. TI suggests the following evaluation boards as a guide for high frequency layout and as an aid in device testing and characterization.
