Rail-to-Rail Operation
The LT1218/LT1219 differ from conventional op amps in
the design of both the input and output stages. Figure 1
shows a simplified schematic of the amplifier. The input
stage consists of two differential amplifiers, a PNP stage
Q1/Q2 and an NPN stage Q3/Q4, which are active over
different portions of the input common mode range.
Lateral devices are used in both input stages, eliminating
the need for clamps across the input pins. Each input stage
is trimmed for offset voltage. A complementary output
configuration (Q23 through Q26) is employed to create an
