Rail-to-Rail Characteristics
The LT1806/LT1807 have input and output signal range
that covers from negative power supply to positive power
supply. Figure 1 depicts a simplified schematic of the
amplifier. The input stage is comprised of two differential
amplifiers, a PNP stage Q1/Q2 and a NPN stage Q3/Q4 that
are active over different ranges of common mode input
voltage. The PNP differential pair is active between the
negative supply to approximately 1.5V below the positive
supply. As the input voltage moves closer toward the
positive supply, the transistor Q5 will steer the tail current
I
1
to the current mirror Q6/Q7, activating the NPN differ-
ential pair. The PNP pair becomes inactive for the rest of
the input common mode range up to the positive supply.
A pair of complementary common emitter stages Q14/
Q15 that enable the output to swing from rail to rail
constructs the output stage. The capacitors C1 and C2
form the local feedback loops that lower the output
