0.8V of either rail when driving a 2k

Ω 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.
