LINEAR INTEGRATED CIRCUIT

QW-R105-029,A

PHASE INVERSION

At high differential input voltage, the UTC 3422 keeps the right output level thanks to its specific input structures.

The advantage is obvious on the following figures and can be also an advantage in linear use when saturation might

occure.

Figure 5 & 6 show the behaviour in follower stage with saturation output of UTC 3422 versus 15MHz standard

operational amplifier.
