Circuit Description
The LT1800 has an input and output signal range that
covers from the negative power supply to the positive
power supply. Figure 1 depicts a simplified schematic of
the amplifier. The input stage is comprised of two differ-
ential amplifiers, a PNP stage Q1/Q2 and an NPN stage Q3/
Q4 that are active over the different ranges of common
mode input voltage. The PNP differential pair is active
between the negative supply to approximately 1.2V below

the positive supply. As the input voltage moves closer
toward the positive supply, the transistor Q5 will steer the
tail current I

to the current mirror Q6/Q7, activating the
NPN differential pair and the PNP pair becomes inactive
for the rest of the input common mode range up to the
positive supply. Also at the input stage, devices Q17 to
Q19 act to cancel the bias current of the PNP input pair.
When Q1-Q2 are active, the current in Q16 is controlled to
be the same as the current in Q1-Q2, thus the base current
