Most individual op amp devices are optimized for either DC precision or for high speed operation. A composite amplifier configuration uses a precision low offset and drift amplifier to control the dc biasing of a high speed amplifier. This circuit has a gain bandwidth product of 1.25MHz yet an input offset voltage of only 25uV maximum.
