DESIGN FEATURES 200ВµA, 1.2MHz Rail-to-Rail Op Amps
Have Over-The-Top Inputs
by Raj Ramchandani
Introduction
The LT1638 is Linear TechnologyвЂ™s
latest general-purpose, low power,
dual rail-to-rail operational amplifier;
the LT1639 is a quad version. The
circuit topology of the LT1638 is based
on Linear TechnologyвЂ™s popular
LT1490/LT1491 op amps, with substantial improvements in speed. The
LT1638 is five times faster than the
LT1490. The LT1638/LT1639 are
вЂњtoughвЂќ op amps, with a variety of
features that make them ideal for
general-purpose applications. A
unique input stage allows the LT1638
to be operated with input common
mode voltages up to 44V above the
negative rail. The LT1638 dual and
LT1639 quad op amps operate on all
single and split supplies with a total
voltage of 2.5V to 44V. These amplifiers are reverse-battery protected and …
