Rail-to-Rail Input and Output
The LT1498/LT1499 are fully functional for an input and
output signal range from the negative supply to the posi-
tive supply. 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 ranges of input com-
mon mode voltage. A complementary common emitter
output stage (Q14/Q15) is employed allowing the output
to swing from rail-to-rail. The devices are fabricated on
Linear Technology’s proprietary complementary bipolar
process to ensure very similar DC and AC characteristics
for the output devices (Q14/Q15).

The PNP differential input pair is active for input common
mode voltages, V
CM
, between the negative supply to
approximately 1.3V below the positive supply. As V
CM
moves further toward the positive supply, the transistor
Q5 will steer the tail current, I
1
, to the current mirror Q6/
Q7 activating the NPN differential pair, and the PNP
differential pair becomes inactive for the rest of the input
common mode range up to the positive supply.
The output is configured with a pair of complementary
common emitter stages that enables the output to swing
from rail to rail. Capacitors C1 and C2 form local feedback
loops that lower the output impedance at high frequencies.
